Although originally a few meters shorter than the great pyramid, Cephren's pyramid appears greater than that of Cheops primarily because it stands on higher ground. This pyramid was built by Khafraa, king Khufu's son. The smooth stone finish that encased this pyramid remains intact only towards its peak but has otherwise completely eroded. This top part gives the viewer an idea of how the pyramids looked before erosion. While its inclination angle is about 53 degrees, its original height is 143.5m and the length of each of its four sides is 215.5m. In its northern facade there are two entrances; one is 11m above the ground, while the other is cut out in the rocks at the ground level. Both these entrances lead to a room called "the burial room". In the western side of this room one may find the king's coffin, which is made quite skillfully of polished granite. The length of that coffin is 2.6m, its width is 1.5m and its height is nearly one meter.
