There is plenty to discover at the ruins of Hierapolis above Pamukkale, which date back to 190 BC, when the ancient city was established by the King of Pergamum, Eumenes II. Prosperous under the Romans and the Byzantines, it was only abandoned after a major earthquake in 1334. Begin at the Hierapolis Archaeology Museum, in the former Roman Baths, where you can see the ruins of a Byzantine church and the Temple of Apollo, then head for the stupendous Roman theatre, which could once hold some 12,000 spectators. Restored in the 1970s, it has some pretty decorative panels and you can make out the VIP seats in the front row.
Further up the hill, you’ll find the octagonal shaped Martyrium of St Philip the Apostle, where it’s thought Saint Philip was martyred, and spectacular vistas of the site, including another ruined theatre dating to Hellenic times and a large 2nd century agora or marketplace. Back down the hill, don’t miss the Appian Way of Hierapolis, a sprawling necropolis with a cluster of tombs, some topped by phallic symbols.
