The Pyramid complex of Userkaf was built c. 2490 BC for the pharaoh Userkaf (reign 2494–2487 BC), founder of the 5th dynasty of Egypt (c. 2494–2345 BC). It is located in the pyramid field at Saqqara, on the north-east of the Step pyramid of Djoser (reigned ca. 2670 BC). Constructed in dressed stone with a core of rubble, the pyramid is now ruined and resembles a conical hill in the sands of Saqqara.
