Hierakonpolis, the Predynastic capital. Pharaoh Khasekhemui (2690 BC) was buried at the necropolis at Umm el-Qa'ab in what was once described as the earliest stone structure in Egypt. the quality of the construction was so primitive. Especially compared to the step pyramid of Djoser at Saqqara, which has been dated to the start of the third dynasty. Khasekhemui’s skeleton was never found, suggesting it was looted long before the excavation.
