Alongside St John’s Basilica and the Isa Bey Mosque the Ayasuluk Fortress sits atop Ayasoluk Hill and dominates the skyline of Selcuk. The fortress was built to protect St John’s Basilica and the ruins represent Byzantine, Seljuk and Ottoman periods. As well as the partially restored walls of the fortress there are remains of houses, a mosque, baths, a hammam and cisterns.

Things to do in Ephesus and Selcuk tip: Isa Bey Mosque, St John’s Basilica and Ayasuluk Fortress are located close to each other so combine a visit to the three.
