This hill (147 m high) was in Antiquity consecrated to the Muses and named Mouseion. On the way up, note a troglodytic dwelling for a long time identified as Socrates' prison. The hill is dominated by Philopappos' monument (116 A.D.), built in memory of a prince of Syrian origin, a Roman consul and benefactor of Athens. Fine views of the Acropolis, Athens, the Hymetus and the Attic go as far as the Saronic Gulf. Don't miss the Dora Stratou folk dances in Philopappos' theatre!
