The Egyptian site of the unfinished pyramid of the 4th Dynasty ruler Djedefra (Redjedef) (c 2566-2558 BC), the third of the seven kings of that dynasty. The pyramid, situated northwest of Giza on the west bank of the Nile, appears unfinished because the walls to the mortuary temple next to it were hastily made of mud brick instead of the usual cut stone. The complex was deliberately ransacked as Djedefra was involved in a dynastic struggle. An Early Dynastic (c. 2925- c. 2575 BC) private cemetery has also been found at Abu Ruwaysh.
