The Pyramid of Djedefre consists today mostly of ruins located at Abu Rawash in Egypt. It's Egypt's most northerly pyramid, and is believed to be built by Djedefre, son and successor to king Khufu. Originally it was thought that this pyramid had never been completed, but the current archaeological consensus is that not only was it completed, but that it was originally about the same size as the Pyramid of Menkaure — the third largest of the Giza pyramids. It is believed to be the most beautiful of the pyramids, with an exterior of polished, imported granite, limestone and crowned with a large pyramidion. It is also believed for this reason the completed pyramid was largly deconstructed by the Roman Empire to build their own construction projects after the conquest of Egypt under Roman Emperor Augustus.
