Kind: captions Language: en [Music] the Great Pyramid one of the most studied ancient riddles on Earth yet questions still remain there were tens of thousands of people here building the pyramids where's their settlement 6 million tons of stone shaped and transported over 30 years to build an eternal tomb with a sacred purpose and creating This Magnificent Monument they were going to have access to the afterlife now stunning new discoveries are revealing lost secrets about the structure there's another void and that void exists right through this Granite wall about those who created it they actually called themselves the elite and about how their King mobilized a proud and willing Nation like the space program there was a sense of national pride and achievement to overcome Monumental disasters they're trying again and again and again until they get it right and achieve the greatest feat of Precision Engineering of the ancient world it's perfectly level it's a remarkable achievement this is how the Great Pyramid United a nation that would become one of the greatest civilizations of antiquity I think not about how the Egyptians built the pyramid I think more about how the pyramids build Egypt decoding the Great Pyramid right now on [Music] Nova as an american-based supplier to the construction industry car is committed to developing a diverse workplace that

human civilization building awe inspiring monuments temples and tombs demonstrating remarkably precise engineering all to honor their pharaohs as living gods many were crowning achievements of the Old Kingdom the first great flowering of Egyptian art that began 4,500 years ago the Pyramids of Giza stand as enduring and mysterious relics massive structures raised to ensure the after lives of three all powerful pharaohs menare cafre and kufu the pharaoh who built the oldest and the biggest pyramid of all the Great Pyramid the last surviving wonder of the ancient world the Great Pyramid is a testament to ancient Egyptians Ingenuity aimen and Technical and scientific prowess the great p is absolutely elegant and marvelous even by standards today how did the Egyptians engineer this enormous Monument with such extreme Precision using only the most basic of tools and brute human power who were the thousands of laborers who toiled for decades on this massive project and how did building the Great Pyramid transform ancient Egypt now after Decades of intense research experts have uncovered a wealth of new evidence about the construction of the Great Pyramid from archaeology from ancient texts and even from understanding the engineering of the pyramid the people of the pyramid are coming back to life for us when it comes to telling the story of the pyramids it's never been easy to separate fact from fantasy the silent Enigma of the pyramids can be like a blank canvas ready to accept the latest outlandish theory about its Builders such theories drew a young woodb archaeologist to Egypt in the 1970s I came with so-called New Age ideas about the pyramids believing that they had something to say about the lost continent of Atlantis and so on and when I encountered Bedrock reality at the Giza Plateau it didn't add up to those ideas now after four Decades of Investigation Mark laner has become one of the world's leading Authorities on the Giza Pyramids his work has focused on Illuminating the lives of the workers from sifting through an ancient garbage dump to Excavating a highly ordered City that housed the [Music] laborers he's found evidence of a massive effort that transform the Old Kingdom I think not about how the Egyptians built the Pyramid I think more about how the pyramids built Egypt the pharaoh kufu ordered the construction of this engineering Marvel as a monument and tomb for all eternity and yet we know very little about the man himself this tiny statue is the image of the man who made one of the largest buildings in the ancient world it's extraordinary that someone who has left us the Great Pyramid which is still standing nearly 5,000 years after it was built we still don't have that much of the man himself for thousands of years the only record of how kufu built the Pyramid came from the world's first historian Herodotus who wrote a history of Egypt in around 450 BC it describes kufu as a wicked and selfish King per perhaps not a very reliable account considering kufu had been dead for 2,000 years Herodotus wrote about the Great Pyramid as of course who wouldn't because he came here as a historian and a tourist he also of course like any good tourists listened to what the various tour guides said and some of them were not very complimentary about hufu um and they accused him of being a terrible mean King harus account provided Hollywood with a box office ready story that kufu brutally enslaved his laborers to build his Grand [Music] Monument egyptologists like Mark laner believe this story is too simplistic but to reach a deeper understanding Mark first had to shift his perspective I realized I had to turn my back to the pyramids to properly understand them because to properly understand them you need to know about the people who built them their civilization their society there were tens of thousands of people here building the pyramids where's their settlement and that led us to look to the far south Southeast in the 1990s Mark collaborated with renowned Egyptian archaeologist zahi Haas on a remarkable [Music] Discovery just south of the Great Pyramid and on the edge of modern-day Cairo they uncovered the footprint of an ancient lost city the remains of streets Barrack likee buildings bakeries storage facilities even what looked like guard houses gradually emerged from the sand pottery and other artifacts dated it to the fourth Dynasty 45 centuries ago the time the pyramids at Giza were built Mark estimates that long galleries resembling dormitories could have housed more than 2,000 people and they were just part of a much larger City that Now lies under modern-day Cairo the whole thing looks like an early version of institutional buildings like our hospitals schools prisons Mark has recently investigated a huge ancient Egyptian garbage pit on the edge of the lost city that the surface of Cromer's uh excavation this garbage dump originally excavated by Austrian archaeologist Carl chromer is now being intensively reexamined by Mark Lan's team so here is the gravel that's left behind even after we SI now most archaeological projects I dare say just throw this away way they're done with it but we couldn't do that because we saw that it's full of information it may appear to be just a pile of sand but it has revealed unique insights into the everyday lives of the people who lived and worked on the Giza [Music] Plateau we're getting quantities and quantities of of pottery even this clean sand is showing all this kind of material objects of everyday life pottery and Clay seals suggests that this debris comes from an earlier period of the lost city dating back to the time that kufu was building the Great [Music] Pyramid this vast collection of new finds from both the dump and years of excavations at the Lost City is being processed at the team's lab situated in the shadow of the pyramids in this door space we have all of the artifacts all of the material culture that's come from the excavations and it is probably millions of items we've listed hundreds and thousands of Flint tools we have dozens and dozens of large Stone Pounders we have broken seal Impressions from seiling and opening and closing boxes and doors we have metal working waste from probably resharpening and reworking copper tools among the finds is evidence that some of the great pyramid's workers were highly skilled it takes a particular knowledge and skill to make a blade like this this may well have been used for scraping things it's also possibly used as a cutting tool so there almost certainly would have been specialized workers providing tools for the workers who were building the pyramids so it's a complete Network everything fits together like this if you haven't got the Craftsman to create the tools to provide the people who are going to build the pyramids the whole system falls apart other discoveries revealed there were thousands of bakeries indicating the mass production of food we have bread molds and this is the largest size we have and this is part of the evidence that they're doing things on a really massive industrial scale cuz this would have fed six or seven men just the bread made in this one mole archaeologist Richard reading estimates that enough cattle sheep and goats were regularly slaughtered to feed thousands providing a diet much better than slave rations so they're getting a lot of food but they're requiring their bodies are requiring a lot of protein they're working very hard they're moving rocks they work from sunrise to sunset and we estimate they were getting uh almost uh 300 gram a day between 2 and 300 gram a day of meat which is about uh probably a Big Mac or a quarter pounder with cheese it's a far cry from the vision and popular imagination of an army of unskilled disposable and malnourished slaves the public thinks that slaves made the pyramids and it's very annoying because they were well looked after because there's no point in having a Workforce that can't work so really it was in the interest of hufu to have a happy wellfed well organized and healthy Workforce but if they weren't slaves who were they egyptologists believe there was a readily available Workforce and they weren't all full-time builders most were farmers working the fertile banks of the River Nile they would plant in late November December the crops would grow and then just about when it started getting warm in the springtime they would Harvest but for 3 to four months of the year that rural activity had to stop seasonal rains high up in the Ethiopian and Nubian Highlands flowed into the branches of the Nile swelling the river and swamping the surrounding Farmland every year the annual n flood turned the Nile Valley and the Delta into one big lake normal agricultural life during the flood season became impossible so for 4 months of the year the land is flooded what are your peasants going to do probably they go down to the tavern and have a drink or two two or more and start criticizing the government the floods gave kufu a predictable source of seasonal labor they get fed they get cared for they get some payment they also feel involved and there's a sense of national pride so in a way building a pyramid is a smart move the artifacts une Earth suggest that while many laborers took on heavy lifting jobs thousands more were involved in other ways we've got estimates that suggest that there were more people involved in raising the food to feed the pyramid Builders than they were here working actually on the pyramids so um the I think I've got an estimate of over 1500 individuals directly involved in raising sheep over another 500 directly involved in raising cattle that's 2,000 people uh you can add them to what uh the feeding the raising of of Wheat and barley to make the bread Mark estimates that along the length of the Nile over 20,000 people played a role in the supply chain that ended at the construction site on the Giza Plateau building the Great Pyramid must have had a dramatic effect on these 1 million plus people living in the Nile Valley at that time adjusting for population it would be the equivalent of almost 10 million modern-day Americans recruited to work on a single project I think that certainly there are State projects where people try to get this feeling a sense of national pride and achievement so you know when the US had its space program there was a sense of national pride and achievement even if not every individual was involved in it Mark laner believes the evidence that the workforce was well organized cared for and skilled makes sense considering the audacious scale and precision of the construction [Music] project but although the Great Pyramid is the biggest pyramid ever built it wasn't the first it was based on 80 years of trial and error by kuf Fu's predecessors the first Egyptian pyramid was a step structure built by the architect imotep for the burial of the Pharaoh joser around 2560 BC it consisted of six tiers rising to almost 200 ft then around two decades later came kufu father the Pharaoh sneferu his likeness now preserved in the Egyptian Museum in Kyo he launched a campaign of pyramid building on an unprecedented scale SRE was the most prodigious pyramid builder of all time he built three great monuments known as the maum pyramid the bent pyramid and The Red Pyramid in building those three giant pyramids he basically did all the research and development that led to the Perfection of the Great Pyramid of kufu at Giza but as he began building the first true smooth pyramid snaro ran into trouble the bent pyramid is named after the abrupt Bend in the angle of its sides they made the slope too Steep and the structure kept threatening to collapse so twice they changed their plan and reduced it to a safer angle they're trying again and again and again they're doing successive drafts until they get it right the lessons learned during sneferu's building campaign would eventually lead to the Great Pyramid kufu took what snfu did to the next level but certainly without sfu's work kufu would not have been able to achieve such a stupendous Monument everything about the Great Pyramid is exceptional even by modern standards it's an engineering phenomenon the Precision of its planning began before a single Stone was laid on sight its base is a near perfect square each side measuring 756 ft covering an area the size of seven Manhattan blocks it's as tall as a modern 44 story building and it weighs some 6 million tons when the tourists come here inevitably they take a look at the Great Pyramid and they look up and they look up with awe from an engineering point of VI when you come to a place like this to look down because the clues of how they built the Pyramid are written in stone on a scale of acres here although it is 4,500 years old it was built with astonishing accuracy at the base of the monument engineer Glenn Dash finds evidence that the foundations were meticulously prepared before construction began we're now standing on the Bedrock and originally the Bedrock sloped at a 6° angle from the Northwest to the southeast they carved all of that way with only simple tools the ancient engineers carved an almost perfectly level flat Foundation into the sloping Giza Plateau but that still wasn't good enough to build the perf pyramid they would lay out underneath the Bedrock a platform the platform itself is one of the miracle of the pyramids despite its unassuming appearance this Stone platform is one of the pyramid's most impressive and critical engineering Marvels it's perfectly level over its entire periphery almost a kilometer to within plus or minus 1 in that was one of the keys the perfectly flat perfect platform to build the perfect pyramid Dash's survey reveals that the base and sides of the pyramid are aligned to the north south east and west to within a fraction of a degree but in a time before the invention of the magnetic compass how could The Architects have laid out the square base of the pyramid accurately Glenn has a theory you simply take a stick and you stick it in the ground the stick doesn't have to be straight it doesn't have to be vertical you just have to do the test on either the spring or the fall equinox the equinoxes are the two days each year that fall midway between Midsummer and midwinter and ancient Egyptian Sky Watchers would have noticed that on those days the sun rose and set directly east west casting a near perfect West East Shadow line as it passed Glenn argues that by marking the tip of that shadow as it moved with stones for example The Architects could lay out an accurate east to west line if you do that you get the kind of accuracy that the Egyptians have achieved when they align their pyramids 1/10th of one degree it's a remarkable achievement but why put so much effort into aligning the pyramids so accurately like like every aspect of its design the orientation of the pyramid had symbolic significance it mirrored the pharaoh's own Supernatural alignment with the sun god raw the afterlife of the Pharaoh was modeled on the afterlife of the Sun so it was the similarity between the life cycle and resurrection of the sun and the life cycle and resurrection of the king that leads us to believe the pyramid was primarily a solar Monument the birth and death of the sun each day was at the heart of ancient Egyptian religion if burial rights were performed correctly the son and Osiris the god of life would merge with the king's soul to be reborn according to egyptologist Sala ikram each evening the Son and the King's Soul traveled together to the Underworld the the ancient Egyptians believed that you lived forever now if you were a king you had responsibilities because you were not just a human being you were a God and as such you were Son Of The Sun God and you are Allied to the Sun God and of course without the Sun the world doesn't function the Great Pyramid and the king's tomb deep inside it was the starting point for the pharaoh's Resurrection reenacted each evening as the sun god and the King's Soul disappeared below the Western Horizon and began their nightly Journey Through the underworld when the sun did battle against the forces of darkness and evil and apois the King was with the sun god almost fused with him [Music] the king went across the night sky battling against the Demons of darkness and then had to emerge we hope Victorious the next day so that Egypt would live so that the land would flourish and that life would continue the Great Pyramid was built to house and protect the king's precious mummified body during his eternal battle for the world's survival and prosperity inside are three chambers joined to the outside by a network of passageways none of these internal structures were ever meant to be seen once the pyramid was complete nevertheless they are built with the same precision and attention to detail as the huge platform the pyramid sits on at the heart of the pyramid is a granite tomb where the dead King's mummified body would lie for eternity we're in the king's chamber more or less in the heart of the pyramid here is essentially this great Granite line box built for the most part to contain the body of the king this chamber would be the starting point of the pharaoh's cycle of death and rebirth for Egypt's continued survival this tomb needed to last forever so the engineers turned to one of the strongest Stones available to them Granite it must have made s s in a magical way what we would call Magic there must have been spiritual power that made them take these choices building this magical chamber would pose an unprecedented challenge to the ancient engineers they didn't want the weight of the pyramid the pyramid that was meant to protect the king and ensure his resurrection so that the weight of the pyramid wouldn't actually crush and Destroy his mummy because if you destroy the mummy the whole magical machine is broken but the ceiling of the king's chamber is flat a potential structural weak point all of the weight of the stone between this ceiling and the top of the pyramid would be bearing down on this flat surface with no support in the chamber below to hold it up yet 4,500 years later it is still intact how is that possible in 1837 a British antiquarian Major General Howard Vice solved the puzzle by discovering what was above the granite slabs that formed the flat roof he actually put Reed through the cracks of the great beams and it went into dead space empty space What Vice did next was highly destructive so he had his workers blast their way up making a vertical tunnel Vice used gunpowder to blow a series of holes up through the heart of the pyramid and discovered not one hidden chamber but a stack of five empty Granite roof spaces and at the very top a large sloping gabled roof they used big Limestone beam and they put them in a gabled pattern to we think so that the weight of the pyramid would be thrust away from this stack of Chambers and from the king's chamber below the gabled roof on top of the secret stack of Chambers relieved the downward stresses on the sacred tomb's flat roof and instead deflected the weight of the pyramid away from the king's chamber by today's standards it may have been an excessively cautious solution but they couldn't afford to take risks they were over engineering because they had never really done this before so that the pyramid the very thing that was meant to protect the king and ensure his resurrection would not collapse and crush his mortal remains kufu Engineers had learned from the mistakes his father snu had made and they pushed ancient architecture to the Limit turning the Great Pyramid into a unique Monument kufu was the first and the last to attempt this uh audacious engineering and so for that the Great Pyramid although it's the classic pyramid in the popular imagination is actually the most unusual it's a huge anomaly despite the unprecedented effort invested in kufu Great Pyramid no records were ever found describing the details of this vast building operation until now in this Barren landscape archaeologists have discovered a unique written record but this isn't Giza it's over 150 M away at a place called Wadi El jar on the edge of the Red Sea it's here that in 2013 archaeologist Pierre tall was investigating the remains of the world's oldest port dating to the Old Kingdom it played a crucial role in the pharaoh's Monumental building projects to cut massive Stones the builders needed high quality metal tools the only metal readily available to the Egyptians was copper which was mined in the Sinai and fed across the Red Sea to this port at Wadi El jarf Sinai is the main place where Egyptian were able to fetch Copper at that time and when you are building huge structures in limestones like pyramids you dramatically needs copper Pierre and his team began to to excavate around the boat houses where ships were stored when not in use they then made a surprising discovery first we came across Big lsone Blocks it was inscrib with name of kufu it was an important find since so little evidence from kuf Fu's Reign has survived but nothing prepared them for what they found next it was a real surprise we have got small pieces of papar Pierre and his team had discovered a cache of fragile ancient documents on paper made from reads called papy covered in Egyptian hieroglyphs including many examples of the same Royal Insignia a cartouch an oval frame with the name of an ancient Egyptian pharaoh inside that name was kufu the C of kufu is quite everywhere these are the world's oldest Papyrus texts in 2017 Pierre T published the first volume of his analysis of these ancient writings amazingly they offer the only firsthand record of the building of the Great Pyramid you have the name ofu the horizon kuu aket kufu The Horizon of kufu in ancient Egypt the word horizon can mean mountain of light somewhere where the sun rises or sets and the Horizon of kufu was the name the ancient Egyptians gave to the sacred Great Pyramid we have this words I think maybe more more than 100 times we were excited it was a yeah kind of a dream dating to year 27 of kufu Reign the papy lists details of the times dates and deliveries of cargo to the pyramid site suddenly here are these Excel spreadsheets of ancient times and Papyrus giving us accounts of what kuf Fu's workers received we have a diary and a log book that's what makes theel jarf papay so much more significant among the entries are records of meetings with senior officials and the time it took to deliver a cargo there was even a note in reding that someone had fetched a large supply of bread for the crew these papy are fabulous because they give us this sort of Slice of Life and it just gives you a sense that throughout Egypt there would have been these little hives of activity and people keeping the same kind of account and by putting it all together you get a much bigger picture the papy were written by the overseer of a work team that delivered the [Music] stone a man whose name was merror and Mer's handwritten notes record how he and his crew of 40 men sailed the Nile his was one of several ships delivering fine quality Limestone to the construction site from the quaries of Tura 10 mi from Giza but how did they deliver the stones from the Nile to the site over 100 ft higher on the Giza Plateau the papy referred to artificial basins and harbors that merror encountered as he approached the construction site when m and his team arrived in Giza we have information about the artificial lakes that were made to allow boats to deliver raw material for the building of the pyramid today the Giza Plateau sits on the edge of modern-day Cairo traces of the artificial basins recorded by mirror have been found underneath these streets and thanks to the Papyrus we now know the ancient name of one of them Ros kufu the entrance to the Basin of kufu when the Nile floods filled this man-made pool a navigable path opened between the river and the Giza Plateau so we now know that the major influx of material both gigantic Stones Timber wood grain to feed the people happened during the flood season when the Nile Rose and covered the valley and filled the Deep Channel where it Rose more than 7 m and they used this system of basins and waterways almost like a hydraulic lift to bring the materials needed for Pyramid building if Giza was the Beating Heart of the pyramid project then its lifeblood was the River Nile its annual floods not only freed up a national Workforce but enabled the laborers to deliver supplies all the way to the foot of the pyramid site the Great Pyramid could not really have been built if Egypt did not have the Nile and a complex system of waterways connecting the land because at this time the terrain isn't good enough we don't really do wield Vehicles remarkably archaeologists at Giza have discovered the remains of two boats from the time the artificial Waterfront at Giza was at its Zenith one has already been carefully restored from the 12200 pieces recovered by archaeologists who believe that it was a ceremonial boat crafted to transport kufu in his journey through the afterlife while the second is now being meticulously excavated under the watchful eye of project consultant Muhammad ABD El MCU [Music] now they are extracting the woods of the second boot all of this will constitute the the boat itself the hull and the um deck and also the super structure which is which is the canopy [Music] itself these Timbers provide a fascinating glimpse of ancient Egyptian boat building methods these same techniques that we can see on this on a ceremonial boot were used for the transport boot they brought the stones from Torah to here or from asan to here building the pyramids not only involved transporting thousands of stones up the Nile but also required importing Copper from the Sinai which meant sailing across the red to the port at w El jarf Mohammad believes these Timbers reveal a cunning design feature that allowed meor and others like him to use the same boat on bodies of water separated by 15 Mi of desert he will cut V shaped channels in a 45° Direction and the other one in the other direction so he can pass through these ropes from one side side to the other these holes weren't cut for wooden or metal fasteners because ancient Egyptian ships were held together with rope when we look at the kufu boat we see that here's a ship with elegance and amazing engineering but that's entirely stitched together with mortis and Tenon joins and by ropes that interlace through all the parts of the hall for example by using ropes instead of nails teams could dismantle their boats and transport them across the desert to where they were next needed they took the parts from the Nile Valley across to the Red Sea Coast piece by piece then they would put the parts together they would basically Stitch the whole ship together sail across to Sinai get their loads of copper bring the copper back copper is a relatively soft metal prone to wearing down the amount of copper required for tools on the job site must have been tremendous but nothing compared to the hundreds of thousands of tons of stone demanded by the builders meeting that need would have been a massive logistical challenge made even more difficult because the Great Pyramid is actually built of three different types of stone the exterior was an outer casing of high quality white Limestone concealing a much rougher inner core of course common Limestone and then deep within the pyramid the complex of granite Chambers reserved for the sacred Tomb of the king and that meant millions of tons of stone had to be shipped to the site the rough Limestone for the core came from a quarry just 500 yd south of the pyramid platform while the pyramid's highquality casing Stones were brought by meor team and other work gangs from nearby Tura meanwhile the stone for the king's chamber had to be shipped from the major Granite Quarry in Egypt at Aswan some 500 M south of Giza these different types of stone all had to be delivered at around the same time because because all the sections of the Great Pyramid were constructed simultaneously they built them in stages incrementally and then filled in the mass of the pyramid around them step by step almost like 3D printing these days all the elements of the pyramid the casing the core and the internal Chambers would rise as one from the Giza Plateau but as the pyramid grew how did the builders manage to raise the blocks up the rising and sloping sides of the monument by looking at what uh seems to be in its loose State just Rubble we can have an understanding of how they built the pyramids because they formed this Rubble into ramps and embankments some of which like this one remained together until this day probably they envelop the entire pyramid with big embankments like this but this was before ancient Egypt had the we their solution was well suited to the desert terrain it doesn't look very pretty but it's really important because this is one of the key um sort of tools that was used to make the Great Pyramid it is in fact a sledge and you can use them on sand as well as snow and so here we have this big sledge that would have been used to take Lo the large rocks on them and pulled by teams of men up through the causeway up the ramps to build the Great Pyramid for the people of Egypt this backbreaking work was a physical investment in the spiritual future of Egypt their contribution to ensure the Pharaoh would be successful in his journey through the afterlife and they did it all with just the most basic of [Music] equipment it's extraordinary to think that it was built with the very simple tools you had wood rollers you had rope you had hard Stone on soft stone and you had a few metal tools and most importantly you had the brains and the brawn of human beings and that's all that they had during the annual Nile flood the construction site on the Giza Plateau would have received a constant supply of stone food and tools brought in by ships it was an operation that would strain even a modern supply chain the overseer of all the king's Works had to keep in mind complex Logistics and how to keep this whole Workforce fed healthy and effective what modern contractors call the critical path how to get from the beginning point to the end point and deliver the product meor records give egyptologists a unique insight into how this sophisticated operation worked we were entering the administrative words of the people that were behind the world construction of the of the monument like the Pyramid of Isel the Papi also revealed the name of the man in charge that name was ankh and a stunningly lifelike image of him survives now on display in the Boston Museum of Fine Arts anof was a noble the half brother of the Pharaoh he seems to be at that time the vizer which is the chief of the administration the big bus for the building of the Pyramid of rufu Pierre believes merror may have had several meetings with anof and the papy note that mea's team was part of an elite perhaps because their caros of fine Tura Limestone were highly prized mea was responsible for bringing this Limestone of tah which is of high quality needed to construct all the cing outer casing in of the Pyramid of rufu the outer casing of Tura Limestone gave the Great Pyramid a spectacular appearance today the monument has been almost completely stripped of that outer casing but 4 and a half thousand years ago the smooth white Limestone delivered by people like merror would have covered the whole of the pyramid catching the Rays of the rejuvenating sun in a spectacular display we can think of the Great Pyramid as a colossal special effect clad in white Limestone polished smooth but for them such special effects were not entertainment for them they were they were religious they were magical the magic was a constant reminder of the special religious significance of the Great Pyramid [Music] and the dead King's fight for Egypt's survival for people like merror it was a privilege to be involved in the king's Grand construction project they actually called themselves the elite mayor's group at one point is called in the papayi setup zah The Chosen group it's estimated the people of Egypt spent some 30 years building the Great [Music] Pyramid its last and most enduring mystery is that the mummy of the god King kufu has never been found the granite coffin in the king's chamber is empty many egyptologists believe it was cleared out by tomb robbers in ancient times others speculate that kufu was never buried in his tomb at all if so where might he be in 2017 scientists detected a mysterious void deep inside the Great Pyramid an advanced scanning technique called muan tomography identified a large cavity the size of a 747 fuselage approximately parallel with the king's chamber and that void exists right through this Granite wall at about this level of the pyramid above the grand Gallery leading to this chamber many theories for this mysterious empty space have been suggested it's possible this void which is like a very vague Cloud for us right now is another chamber with Untold Treasures or more importantly documentation like the wal jarf papy but most likely it's dead space that they framed in to relieve the weight of the pyramid on the roof of the grand Gallery just like the relieving Chambers above the king's chamber further investigation May confirm the void is another example of the masterful engineering that's ensured this giant Monument has stood the test of time but even without the pharaoh's body the Great Pyramid continues to ensure kuf Fu's place in history hufu in fact has achieved his immortality to a certain extent we might not have his body but his name lives forever and as each person recites it he is once again given more empowerment in the afterlife and his Great Pyramid does reign supreme through kufu Mighty building project the people of ancient Egypt were drawn into the creation of a magical machine for the pharaoh's Journey Through the afterlife they were creating This Magnificent Monument which also gives you sort of religious um credit because you're helping to build the house of Eternity for your god king The Amazing Discoveries of the W El jarf papy the worker City and the preserved boats reveal the phenomenal planning operation that built the Great Pyramid and unified the people of Egypt into one of the world's first nation states the networks that they created and the national unity and infrastructure National infrastructure that they created for building these giant pyramids that now was what where they devoted their attention and their energies the new evidence shows How kufu Great Pyramid project became the economic engine that drove the first Great era of the ancient world's most vibrant civilization the Egypt of the [Music] Pharaohs [Music] a [Music] [Applause] [Music]
