The Pyramid of Djedefre consists today mostly of ruins located at Abu Rawash in Egypt. It is Egypt's most northerly pyramid, and is believed to be built by Djedefre, son and successor to king Khufu. Though some Egyptologists in the last few decades have suggested otherwise, recent excavations at Abu Roash carried out by Dr. Michael Baud of the Louvre Museum in Paris suggest the pyramid was in fact never finished. If completed, however, it is suggested to have been about the same size as the Pyramid of Menkaure — the third largest of the Giza pyramids. It is believed to have originally been 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 largely deconstructed by the Roman Empire to build their own construction projects after the conquest of Egypt under Roman Emperor Augustus.
