İsa Bey Mosque, Ephesus (must see)
The İsa Bey Mosque, built in 1375 by the order of İsa Bey of the Aydınoğulları Emirate, is one of the finest and oldest examples of Anatolian mosque architecture in Turkey. Located in Ayasoluk, at the base of the hill that holds Ayasoluk Castle and the Basilica of St. John, the mosque draws architectural inspiration from both Seljuk and early Ottoman styles. Designed by the Syrian architect Ali ibn al-Dimashqi, the structure measures approximately 51 by 57 meters and features an asymmetrical layout—uncommon for mosques of its time. Much of its construction material, including columns and stones, was repurposed from nearby ancient ruins such as those at Ephesus and the Temple of Artemis, linking the Islamic monument to the region’s classical past.
The mosque originally had two minarets, although only one survives today, the other having been destroyed by an earthquake. Its western façade, crafted from carefully cut limestone and marble, stands out for its decorative richness and serves as the main entrance. The monumental western doorway is adorned with intricate moldings and an Arabic inscription. Inside, a colonnaded courtyard featuring twelve columns once surrounded a central fountain used for ritual ablution. Three entrances lead to this courtyard, with the eastern and western gates also serving as the bases for the original twin minarets. The interior prayer hall is divided into two aisles, cut by a central transept with domes supported by pendentives, echoing the layout of the Great Mosque of Damascus—a nod to the architect’s Syrian heritage.
The domes of the mosque are embellished with elements characteristic of Seljuk and early Ottoman design, including stalactite (muqarnas) window moldings, turquoise and blue faience tiles, and mosaics. One of the mosque’s most distinctive features is its asymmetry: the placement of windows, domes, and doors was purposefully unbalanced, creating a dynamic, non-linear aesthetic.
Despite falling into disrepair over the centuries, the mosque was restored in 1934 and again in 1970 and 2005, allowing it to continue functioning as an active place of worship. Today, İsa Bey Mosque not only serves as a religious site but also as a testament to the architectural and cultural convergence that defines the region.
