Saqqara
Djoser's pyramid is the oldest complete stone building complex known. It was built in the Third Dynasty. Another 16 Egyptian kings built pyramids at Saqqara: these pyramids are now in various states of preservation. High officials added private funeral monuments to this necropolis during the whole pharaonic period. It was an important complex for non-royal burials and cult ceremonies for more than 3,000 years, well into Ptolemaic and Roman times.
