The mosque features an asymmetric design with two entrances on the western and eastern sides, which was unusual for the period.
Many of the decorative marble elements incorporated into the mosque walls are repurposed spoils from the nearby ruins of Ephesus.
The mosque layout includes a central courtyard known as a 'sahn', which is flanked by arched porticos on three sides.
The building was severely damaged by earthquakes in the 17th and 19th centuries, leading to the loss of much of its upper structure.
The western entrance portal is noted for its intricate geometric stone carvings, a hallmark of the Aydinid architectural tradition.
The mosque is positioned directly between the Basilica of Saint John and the Temple of Artemis, highlighting the layers of historical influence in the region.
İsa Bey Mosque is a 14th-century architectural landmark built in 1374-1375 during the Aydinid dynasty. It is situated on the western slopes of Ayasuluk Hill in Selçuk, constructed by the architect Ali bin Mushim al-Damishki. The structure represents a transition between Seljuk and Ottoman architectural styles, characterized by an asymmetric courtyard plan. Much of the building materials, including marble columns and capitals, were scavenged from the nearby ruins of Ephesus and the Temple of Artemis. The mosque features two prominent minarets, though the northern one is largely destroyed and the southern one has been partially restored. It remains an active place of worship while functioning as an important historical monument. The building was designed with a large courtyard surrounded by a portico, a departure from the traditional enclosed mosque designs of the era.

Combine your visit with the nearby Basilica of Saint John as they are within walking distance.
Remove your footwear at the designated areas before entering the prayer hall.
Visit during the shoulder season to avoid high temperatures, as the open courtyard offers limited shade.
Avoid visiting during prayer times if you are a tourist, as the interior space is reserved for worshippers. Do not climb on loose masonry or structural ruins.
Visitors must dress modestly; women should cover their heads, and both genders should cover shoulders and knees. Maintain a quiet demeanor as it is an active religious site.
