Sakkara Pyramid

The world's first large stone structure built under Pharaoh Djoser founder of the 3rd Dynasty of the Old Kingdom.
Under the Architect Imhotep, the original small mastaba was expanded in all directions to a height of 62 metres, a length of 123 metres and a width of 107 metres. The stone blocks are much smaller than those of the later pyramids.
The pyramid had a casing eventually, though this is now lost.
There are numerous passages under the pyramids where a mummified leg bone of Djoser was found, however the passages are unstable and can no loger be visited.
Djoser's statue was found at the complex and is now in the Cairo Museum. During his reign he was refered to as Horus Netjerykhet and is thought to have been the first to conquer Nubia. His successor Sekhemkhet has a pyramid a couple of hundred metres south, but it is quite damaged yet has an alabaster sarcophagus.
