Name of Monument:

Isa Bey Mosque


Selçuk, İzmir, Turkey

Date of Monument:

Hegira 10 Shawwal 775 / AD 13 March 1375

Architect(s) / master-builder(s):

Architect: Ali ibn el Dımışki [‘Ali ibn al-Dimashqi].

Period / Dynasty:

Aydınoğlu Beylik (Emirate)


Aydınoğlu Isa Bey (r. 761–92 / 1360–90), son of Mehmed Bey, founder of the Aydınoğlu Emirate.


Founded on a hillside in Selçuk, the Isa Bey Mosque occupies an area of approximately 48.68 m x 56.53 m and comprises a prayer hall of two aisles extending laterally, with a rectangular courtyard adjoining it to the north. The east, west and north walls of the courtyard each have a portal. Minarets once rose above the east and west portals, the former of which does not survive. The topography of the site influenced the design of the north and east sides of the building, whose plain walls have few windows. The west and south walls, on the other hand, have two rows of windows. The staircases leading to the west gate are flanked with niches in the wall.
Remnants suggest that the courtyard, which adjoins the north of the prayer hall, had porticoes on three sides and had a fountain. Today only the re-used columns survive from these porticoes. The prayer hall is entered through a triple opening in the middle of the north wall. The entrance is flanked by a pointed arched opening on either side; closed off with glass panes today. The rectangular prayer hall is divided into two aisles running parallel to the mihrab wall and a transverse aisle running perpendicular to it. The side aisles are covered with a pitched roof while the transverse aisle has two domes. The pointed arches, made of brick, divide the prayer hall into two aisles and rest on four granite columns. Three of these monumental columns are topped by muqarnas capitals, the fourth by a re-used capital. The middle two support identical arches which extend to the north and south walls, forming the transverse aisle, which is covered by two domes resting on octagonal drums supported by pendentives.
The north, south and east walls are built, not too carefully, of ashlar, limestone and re-used marble. The monumental west wall, distinguished from the other walls by its design, workmanship and materials, features a portal and two rows of windows, notable for their craftsmanship. The windows, of different dimensions and style, are elaborately decorated with muqarnas, knotwork, inlaid coloured stone and interlace patterns. The marble and coloured-stone decoration on the windows is also used on the fine, tall portal in this wall. Sadly, the rich decoration of the interior has not survived. Today only the geometric compositions, found in the tile mosaic on the pendentives of the dome in front of the mihrab, remain. The original stone mihrab and minbar are also gone.
The Isa Bey Mosque has an important place in Anatolian Turkish architecture, both for its plan and for its decoration. While its plan recalls the Umayyad Mosque in Damascus, the coloured-stone decoration in the portal and windows shows the influence of works from the Zangid and Mamluk periods. These details are connected to the fact that the architect, Ali ibn el Dımışki ['Ali ibn al-Dimashqi], was a Syrian from Damascus. The Isa Bey Mosque is a rare example of Beylik (Emirates)-period architecture seen most clearly in its courtyard with porticoes on three sides, one of the first such examples from before the Ottoman period, and its two minarets.

View Short Description

Modern Selçuk is the medieval Ayasuluğ and the ancient Ephesus. The town was an important centre of the Aydın Emirate and served as its capital from AH 748 to 792 / AD 1348 to 1390. Built by architect Ali of Damascus on the order of Isa Bey, son of Mehmed Bey, in 775 / 1375, the mosque is an important example of 8th- / 14th-century architecture in its plan and decoration. The structure is noteworthy for its layout, which recalls the Umayyad Mosque in Damascus and the Great Mosque of Diyarbakır, and its coloured-stone decoration, which displays Zangid and Mamluk influence.

How Monument was dated:

According to the inscription on the west portal, the architect Ali ibn el Dımışki was ordered by Aydınoğlu Isa Bey to build the mosque on 10 Shawwal 775 / 13 March 1375.
