Ayasuluk Castle, Ephesus (must see)
Perched atop Ayasuluk Hill, Ayasuluk Castle—also known as Selçuk Castle—commands sweeping views of the surrounding countryside and stands as a silent witness to centuries of shifting empires. Just a mile from the ancient city of Ephesus, the castle was constructed by the Byzantines in the 6th century using stones from earlier Greek and Roman structures. It was part of a broader defensive strategy as the once-thriving harbor city of Ephesus began to decline. The Byzantines built the citadel to protect the Basilica of Saint John, which lies on the southern slope of the hill, effectively transforming the area into a fortified religious and administrative center.
The castle's massive stone walls, some 4 meters thick and stretching 1.5 kilometers in circumference, were reinforced by 17 towers and accessed through the Gate of Persecution. This gate led first into the basilica, a place of great spiritual significance, believed to house the tomb of St. John the Apostle. Over time, the population migrated uphill toward this citadel as the Ephesus harbor silted up and malaria plagued the lower city. By the time the Seljuk Turks captured the site in 1090, it had become little more than a small village, though it later experienced a resurgence when the Seljuks repaired the walls and dredged the harbor.
Throughout the centuries, Ayasuluk Castle remained a key strategic and religious site. Under the Seljuks and later the Ottomans, it served as a military garrison and administrative hub. In the 14th century, it became the capital of the Aydınoğulları Principality, and despite the harbor's eventual silting again in the 15th century, the Ottomans maintained a garrison into the 17th century. Within the castle today are remnants of its varied past: the partially intact Kale Mosque with its domed roof and minaret, Ottoman-era cisterns, the remains of a Turkish bath, and traces of former residences.
Ayasuluk Castle has two main gates. One is on the east side, and the other, which is used as the tourist entrance, is on the west side.
