The Philopappos Monument is an ancient Greek mausoleum and monument dedicated to Gaius Julius Antiochus.
Philopappos died in 116, and his death caused great grief to his sister Julia Balbilla, citizens of Athens and possibly to the imperial family. As a dedication to honor the memory of Philopappos, Balbilla with the citizens of Athens erected a tomb structure on Muses Hill near the Acropolis of Athens. His marble tomb monument is still known as the Philopappos (or Philopappou) Monument, and the hill is today known as Philopappou Hill
