Asclepion (the ancient medical center) was centuries ahead of its time in its use of therapies to cure ills. Here you’ll find a theater and several sacred pools whose purportedly radioactive waters were used to cure patients. Once accessed via the Sacred Way from the Acropolis, these days you’ll find the Asclepion across town, west of the Bergama Museum and city center.
Other important sites at Pergamon include the Red Basilica and the Zeus Altar.
Bergama (ancient Pergamon) is 100km (62mi) north of Izmir. Pergamon’s sites are spread over a large area and most people choose to see the ancient city on a guided tour.
