 The pyramid of the queen was first recognized in 1928 by C. M. Firth following his first excavations to the south of Userkaf's main pyramid.One year later in 1929, he proposed that the pyramid be assigned to Queen Neferhetepes, Userkaf's wife and the mother of Sahure.It was not before 1943 that Bernard Grdseloff discovered the tomb of "Persen", a priest at the court of Userkaf and Neferhetepes.
