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 Muse Hill (Lofos Muson) near the Acropolis of Athens. His marble tomb monument is still known as the Philopappu Monument, and the hill is today known as Philopappu Hill (Λόφος Φιλοπάππου).
