An unknown ruler ruled between Khufu and Khafre - Djedefre (Radjedef). By all appearances he was a son of Khufu and a Libyan woman. Djedefre allegedly murdered Kawab, the eldest son of Khufu and an Egyptian woman, who was a rightful crown prince. He let build himself a pyramid, which was customary. The pyramid should have been showier than Khufu's to be equal to his successor.
Pyramid construction in Abu Rawash
Pyramid of Djedefre (Radjedef) is the most northerly pyramid of that kind in Egypt, it is located 7.5 kilometers to the north-west from Giza near a contemporary village Abu Rawash. Originally it was called "Djedefre's Starry Sky". Present remains are only little examined. Terrain reconnaissance started in 1842, when Lepsius visited this area. The pyramid was 17 meters high at that time (or rather the remains of it), but it was gradually dismantled in eighties of the 19th century and the stones were transported on camels to Cairo for its development. Today the construction is only 11.4 meters high and only 15 horizontally laid layers of the base are preserved from it.
It is considered, that experiences from the Great pyramid building could be used there. So we can suppose, that the funereal chamber (hole), 24x11 meters, was made from red granite and had flat ceiling. On the other hand a preserved hole with "T" shape and a descending corridor (5.7 meters wide and 48 meters long) doesn't indicate that. This hole is fully filled nowadays.
The base with the ground plan 106x106 meters and supposed gradient of 60 degrees is partly made of stone core and partly of local limestone blocks. The pyramid should have been built with so-called open trench method. The complex around the pyramid remains isn't totally examined, so we don't have detailed information about it.
