Pyramid of Djedefre

The pyramid of Djedefre is Egypt's northernmost pyramid [1]. Believed to have been built by Djedefre, son and successor to king Khufu, it consists today mostly of ruins located at Abu Rawash in Egypt [1]. The destruction started at the end of the New Kingdom at the latest, and was particularly intense during the Roman and early Christian eras [1]. Djedefre's pyramid was architecturally different from those of his immediate predecessors in that the chambers were beneath the pyramid instead of inside [1]. The pyramid was built over a natural mound and the chambers were created using the "pit and ramp" method, previously used on some mastaba tombs [1]. Djedefre dug a pit 21 m × 9 m and 20 m deep in the natural mound [1]. A ramp was constructed at an angle of 22°35′, and the chambers and access passage were built within the pit and along the ramp [1]. Once the inner chambers were completed, the pit and ramp were filled in, and the pyramid was erected above them [1].
