The Giza Plateau is a limestone plateau elevated approximately 60 metres (200 ft) above sea level on the western edge of the Nile Valley near modern Cairo, and it is one of the most studied archaeological sites on Earth. As Gates describes it on camera, the plateau was once part of an ancient necropolis that "back in the day was a mini city of its own" — home to nine pyramids, multiple temples, cemeteries, and the Great Sphinx. The complex's centrepiece, the Great Pyramid of Khufu, stands nearly 45 stories tall, weighs an estimated 6 million tons, is composed of more than 2 million individual limestone blocks, and occupies an area roughly the size of 10 football fields. The plateau forms the northernmost section of a 160 km² pyramid field that is part of the UNESCO World Heritage Site known as Memphis and its Necropolis. Today the site sits on the edge of greater Cairo's expanding urban sprawl, giving it the striking quality Gates notes: it doesn't stand alone in the desert but is surrounded on all sides by a modern metropolis. Gates chose the Giza Plateau as the launchpad for his investigation into the genuine mysteries — and persistent misconceptions — surrounding the Great Pyramid.

Gates investigates the plateau in Expedition Unknown S16E01, "Mysteries of the Great Pyramid," consulting Dr. Mark Lehner
Dr. Mark Lehner is the central expert voice Gates brings to the Giza Plateau. Lehner, who has spent more than 50 years mapping and studying the complex, co-authored foundational reference works on the site and has directed large-scale excavations of the workers' village adjacent to the pyramids — excavations that produced significant evidence about who actually built the monuments and how they lived. His work represents the mainstream archaeological consensus: the pyramids were state-organised construction projects built by a skilled, paid (or corvée) workforce of ancient Egyptians, not by slaves, aliens, or a lost civilisation.
The plateau's statistics alone invite awe without requiring mystery. The Great Pyramid's base covers roughly the area of 10 football fields, its mass is estimated at around 6 million tons, and its orientation to the cardinal directions is precise enough to have generated serious scholarly literature about how the builders achieved it. The plateau as a whole is the northernmost portion of a 160 km² pyramid field in the Western Desert, a landscape shaped over generations of Fourth Dynasty royal ambition.
Within mainstream scholarship, genuine debates do exist: the precise logistics of how millions of limestone blocks were quarried, transported, and placed; the purpose of recently detected internal voids in the Great Pyramid (documented by the ScanPyramids project using muon tomography); and the exact sequence and timeline of construction. These are legitimate open questions that serious researchers continue to investigate — quite distinct from the fringe claims Gates explicitly names and sets aside.
Gates' S16E01 episode contributes by bringing Lehner's expertise directly to a wide television audience and by modelling intellectual honesty: presenting the verified facts plainly, acknowledging what remains unknown, and drawing a clear line between genuine scholarly inquiry and the extraterrestrial or Atlantis-linked narratives that have dominated popular culture since von Däniken. The episode explores rather than resolves, which is an accurate reflection of where the science stands.
The Giza Plateau sits approximately 60 metres (200 ft) above sea level on a limestone formation at the western edge of the Nile Valley.
The plateau is home to nine pyramids in total, not just the three famous large ones — a fact Gates highlights on camera as something that surprises most visitors.
The Giza complex includes not only pyramids and the Sphinx but also temples, multiple cemeteries, a workers' village, and an industrial complex, making it a full ancient urban and administrative landscape.
The plateau forms the northernmost part of a 160 km² pyramid field in the Western Desert, the broader zone designated as part of the Memphis UNESCO World Heritage Site.
The Giza Plateau is generally accessible to visitors as a ticketed archaeological site managed by the Egyptian Ministry of Tourism and Antiquities; entry to the plateau complex, individual pyramid interiors, and the Sphinx enclosure typically require separate tickets. Visitors should check current official advisories for admission fees, permitted access areas, and any interior closure schedules, as conditions change seasonally.
Cairo, Egypt — the Giza Plateau sits on the southwestern edge of greater Cairo, approximately 15–20 km from the city centre.
October through April offers cooler temperatures and is generally considered the most comfortable window for visiting, as summer months can bring intense heat. Early morning visits tend to see smaller crowds before tour groups arrive.

Kingdom of Kush Pyramid Tombs
The Kingdom of Kush pyramid tombs represent a parallel tradition of pyramid-building in sub-Saharan Africa, offering direct comparative context to the Giza complex and its cultural legacy.
Ancient Egyptian tomb (Moses investigation)
Gates' investigation into an ancient Egyptian tomb connected to the Moses narrative places that episode within the same broader Nile Valley archaeological world that the Giza Plateau dominates.
Alexandria
Alexandria, Egypt's great ancient port city, shares the same Nile Valley civilisational sphere and has featured in Gates' investigations of ancient Egyptian and Hellenistic history.
