Philopappou (Filopappos) Athens. Opposite the Acropolis and to the west lies the Philopappou hill. At the top of the hill lies the tomb of the Roman Philopapou. The highest point of the Philopappou hill is at 147 meters. A hike through the green slope is more than worth it, as the view from above is amazingly beautiful. From here you can see Athens well in a wider area and take great pictures.
