The Athenians, after his death, built a majestic monument on the top of the hill to honor his memory, known as the Monument of Philopappou. Ancients called this the Hill of the Muses, as well, because of some temple that existed there.
Besides a beautiful view of the city, this hill played a defensive role in the history of Athens. In 294 B.C., Demetrius I of Macedon (called Poliorcetes) built a fortress on the top of this hill to control the road to Piraeus. In 1867, Admiral Francisco Morozini bombed Acropolis from that position.
These days, Athenians gather there on the first Monday of Lent (official national holiday) for the so called "Koulouma" - that is, the traditional Lenten menu eaten outdoors while flying a kite. On the south side is the Theater Dora Stratou, dedicated to the Greek tradition through the popular (demotic) dances and Songs.
Height of Philopappou Hill: 147 m
