Filopappou Hill and the monument at its summit are both named after the exiled Roman prince, Julius Antiochus Filopappos. Filapappos had strong connections with Roman aristocracy, counting Emperor Trajan as one of his close friends. After being exiled from Commagene, the land over which he ruled, the Prince decided to settle here in Athens. He went onto becoming prominent benefactor, financing greek plays and also served as Roman Consul for the city. He was revered by Athenians, so much so that after his passing this monument was erected in his honour. Completed around 114AD, all that remains are the ruins of this glorious monument, which are still pretty amazing.
