The İsa Bey Mosque is an architectural gem perched at the foot of Ayasuluk Hill in Selçuk. Built in 1374–75, it features cut-stone and marble façades, two large domes, and a single surviving minaret. The grand courtyard, supported by twelve columns and framed by decorative arches, gives the mosque a calm and dignified feel. This historic mosque stands as a symbol of spiritual heritage and design elegance, set against the backdrop of Selçuk’s old town.
Constructed by the Aydınid ruler İsa Bey, the mosque was designed by the Syrian architect Ali bin Mushaimish al-Dimashqi. It covers a rectangular base of roughly 48 × 56 meters, with a large courtyard and adjacent prayer hall beneath two domes. The stonework includes carved geometric and calligraphic designs, while some building materials were repurposed from nearby ancient ruins. One minaret remains from the original two, adding to the mosque’s character.
Visitors should dress modestly and remove their shoes when entering as it is still an active place of worship. Parts of the interior and the courtyard may be restricted during prayer times. The stone courtyard and steps can be uneven, so sturdy footwear is recommended. Bring water and sun protection, especially in summer, as some sections of the mosque are exposed. A quiet moment in the courtyard offers a peaceful break during your sightseeing.
Located just a short walk from central Selçuk, the mosque is easy to access by foot. You can also take a taxi to reach Ayasuluk Hill, where the mosque sits beneath Selçuk Castle. Once there, a paved path leads to the entrance. Nearby parking makes visiting by car straightforward, and its location near other key attractions like the Basilica of St. John and Ephesus ruins means it easily fits into a walking tour.
The best time to visit is early morning or late afternoon, when the lighting highlights the mosque’s delicate stone details and the courtyard remains quiet. During summer, midday can be hot, so aim for softer hours. Visiting just before or after prayer times common in the early afternoon or evening may make certain parts less accessible, but also more atmospheric.
