Koruk Mahmud Ağa Mosque

Koruk Mahmud Ağa, a member of the Nimel Ceyş class, had the mosque originally built as a mescid in the second half of the 15th century.
Over time, the structure fell into ruin and was rebuilt during the reign of Sultan Abdülhamid II. In 1970, it was reconstructed again with slight expansion.
Although sources state that the tomb of the founder is near the mosque, the broken tombstone in front of the mihrab bears no visible name.

The mosque has an almost square plan and a modest appearance with a tiled roof. The last congregation portico (son cemaat yeri) was added later.
The right-side minaret is partially trapped between two buildings; its polygonal base and cylindrical shaft are of equal height. It features a concrete balcony (şerefe) with iron railings and a lead-covered spire. The entrance to the minaret has been opened through a newer building.
Entry to the prayer hall (harim) is through the last congregation area. The right and left walls have three rectangular windows at the lower level and three oval ones above; there are also two-tiered windows flanking the mihrab.
The protruding mihrab, along with the minbar and preacher’s platform (kürsü), are wooden and painted with oil-based paint.
The flat concrete ceiling is whitewashed, and the lower parts of the interior walls are clad in marble.
The courtyard contains an imam’s residence, restrooms, and a building now used as a girls’ Qur’an school. Due to various restorations, the mosque has largely lost its original form.
