The pyramid complex of Userkaf was built for the pharaoh Userkaf, founder of the 5th Dynasty of Egypt. It is located in the pyramid field at Saqqara, on the north-east of the step pyramid of Djoser. Constructed in dressed stone with a core of rubble, the pyramid is now ruined and resembles a conical hill in the sands of Saqqara. For this reason, it is known locally as El-Haram el-Maharbish, the "Heap of Stone", and was recognized as a royal pyramid by western archaeologists in the 19th century.
