The third and smallest of the pyramids, that of king Mycernius, was constructed between 2533 B.C. and 2505 B.C., yet it is characterized by its splendid exterior. Its original height was 66.5m and the length of each side of its base was 108.5m, whereas its angle was 51 degrees. Its entrance is found in the northern side 4m from the ground, leading to a passage and a corridor, which in turn leads to the burial room. In this room, a mummy was found in a wooden coffin, and it is now preserved in the British Museum. Close to Mycernius' pyramid lie three smaller pyramids, the largest of which was thought to belong to Mycernius' principle wife Khamerernebty II. All three of these subsidiary pyramids remained unfinished.
