This mosque was probably built in the 14th century. The building underwent a major restoration between 1992 and 2003. Its modern architect, Turgut Cansever, designed a new mosque that combined the various cultural features of Anatolia without changing the main layout of the demolished structure.

The rectangular mosque is covered with a dome. The windows are rectangular on the ground floor and triangular on the first floor. The harim is covered with a dome supported by triangular pendentives. The interior of the dome is decorated with monochrome glazed tiles. The mihrab is in the center of the south façade, and its recess, which expands downwards, is framed by a rectangular border. To the east of the mihrab is a pulpit made entirely of marble. There is a minaret with a single balcony in the northwest corner. The transition segment lies between the high pulpit and the cylindrical shaft. Further up are the sawtooth eaves under the balcony, followed by the honeycomb gallery topped with a spire.

The most important characteristic of Karakaş Mosque is Cansever’s concept of “vernacular architecture.” The architect used the colorful tiles and stones typical of garden walls in Kaleiçi as building materials. To raise awareness about ceramics, the interior of the mosque was partially covered with tiles. The glazed tiles used on the dome are handcrafted.
