Key facts

• The Step Pyramid of Djoser at Saqqara is generally regarded as Egypt's first large-scale stone pyramid and earliest colossal stone building.
• It stands about 62.5 metres high, with a base roughly 121 metres long and 109 metres wide.
• It was enlarged in stages from a square mastaba-like platform into a six-tiered pyramid.
• Each enlargement enclosed the preceding structure within a new masonry layer.
• The limestone enclosure wall is about 10.5 metres high and has 14 gateways in total.
• Only one gateway is functional; the other 13 are dummy entrances or sculpted façades.
• The underground network extends for more than 5 kilometres and reaches nearly 30 metres below ground in places.
• The main granite-lined burial chamber lies at the bottom of a vertical shaft about 28 metres deep and seven metres wide.
• Recent 3D mapping documented roughly 400 interconnected underground chambers and passages.
• The South Tomb galleries contained more than 40,000 stone vessels.
• The mapped passages form geometric groupings; the video interprets parts of the layout as radiating like wheel spokes.
• The video says some corridors follow astronomical orientations.
• The South Tomb contains a smaller blue-tiled burial chamber modeled on the pyramid's granite burial chamber.
• The video interprets the parallel burial arrangements as deliberate dualism.
• Many underground areas remain unexcavated or inaccessible.
