When he died, his death caused great sadness 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 Mouseion Hill, located southwest of the Acropolis of Athens. His marble tomb monument is known as the “Philopappos Monument”, and from it, the hill became known as “Philopappos Hill”.
