Atik Ali Paşa Camii is a mosque located in Istanbul, along the historic Mese (Divan Yolu) at the Column of Constantine (Çemberlitaş). It was commissioned by the vizier of Ottoman sultan Bayezid II in 1497/902 AH.
The mosque comprises a rectangular domed prayer hall preceded by a five-bay portico. The portico bays are all surmounted by small domes, and the entrance portal is under the central bay. A minaret rises from the west corner of the portico. The entrance portal gives onto the prayer hall, which consists of a large domed central bay, rising above the rest of the building, flanked on two sides by lower aisles, each comprising two domed bays. The southern side of the central domed space is extended by a wide bay covered by a half dome. A large mihrab is built into the back of this bay. Windows at clerestory level and ground level admit light into the prayer hall. Muqarnas squinches make the transition between rectilinear base and half-dome in the southern bay above the mihrab.
