Isa Bey Mosque is one of the most delicate examples of Seljukian architecture, situated below the basilica of Saint John. The mosque was built by the master Syrian architecture Ali son of Mushimish al -Damishki, between the years of 1374 and 1375.
The mosque was styled asymmetrically unlike the traditional style, The location of the windows , doors and domes were not matched, purposely. In the entrance of the mosque, an inscription from the god decorates the doorway. The columns inside the house of prayer are from earlier ruins in Ephesus, making an interesting contrast to the mosque . The domes are ornamented by turquoise and blue faience, revealing the characteristic of Ottoman style. Crown-like doors from Seljukian architectural style later combine with the specific decoration elements of architectural style. The mosque was repaired in 1934.
