The Philopappos Monument (in greek Μνημείο Φιλοπάππου) is an ancient Greek mausoleum and monument dedicated to Gaius Julius Antiochus Epiphanes Philopappos or Philopappus, (65–116 AD), a prince from the Kingdom of Commagene. It is located on Mouseion Hill in Athens, Greece, soutwest of the Acropolis.
In 1898, excavations were carried out at the monument and in 1899 conservation work was undertaken. Archaeologists in 1940, H. A. Thompson and J. Travlos conducted small additional excavations. Recent investigations have certified that architectural parts of Philopappos’ Monument have been used for construction of the Minaret in the Parthenon.
Only two-thirds of the façade remains. The tomb chamber behind the façade is completely destroyed except for the base. The Philopappos Monument appeared to be intact until recently as in 1436, the traveller Cyriacus of Ancona visited the monument and wrote in his memoirs that the monument was still intact. The destruction of the monument must have occurred after this time.
