Located within the borders of Antakya district of Hatay province, within the Urban 3rd Degree Archaeological Site of Antakya from the Ottoman period, Ağca Mosque is situated in Şirince Neighborhood, at the corner where Mete Street and Şekercik Street intersect, on parcel number 1409.

Ağca Mosque is a masonry structure with a courtyard, rectangular plan, single hall, and gable roof. Access to the building is provided through a gateway opening into the courtyard, reached by stairs from Şekercik Street.

In the courtyard, there are facilities such as an ablution area, toilet, muezzin’s room, and a summer prayer hall. The prayer hall, entered through a round-arched doorway from the courtyard, is divided into two aisles by pointed arches built of ashlar stone. The mihrab, which determines the qibla direction, is placed at the center of the long southeastern wall of the building.

The walls of the structure are made of finely cut ashlar stone combined with thickly jointed rubble stone, and the upper part is covered with a wooden gable roof. The roof is clad with traditional Turkish tiles.

Although there is no definite information about the mosque’s original construction, an inscription dated 1842 indicating a repair was present on the structure before the February 6, 2023 earthquake. Examinations show that towards the end of the 17th century, when mosques and masjids with foundations in Antakya were listed, Ağca Mosque was also mentioned among them.

Accordingly, it is understood that Ağca Mosque already existed at the end of the 17th century. The building’s survey, damage and intervention analyses, period analysis, restitution, and restoration projects were prepared by Argos Atölye.
