Ottoman Masjid / Lower Masjid
Locally known as the Aşağı Mescit, i.e. Lower Masjid, the Ottoman Masjid is located in the southwest of the Lower City, approximately 30 m south of the Ottoman Fountain and just above the Aqueduct. It is observed that the superstructure has completely fallen and the main walls of the two-roomed building have been damaged to a great extent. It has a rectangular layout measuring 15.40 x 9.30 m in overall. The southern room measures 9.65 x 9.30 m; the northern room measures 7.85 x 6.10 m. The walls of the northern room have survived relatively in better condition compared to the southern room. The door located in the middle of the northern wall of the southern room was later filled and closed. The entrance doorway in the middle of the northern wall of the northern room and the cancelled doorway, which was later converted to a mihrab niche, are on the same axis. It is noted that the exterior and interior walls of the Lower (Ottoman) Masjid were originally plastered over.

Ottoman Mesjdid
Since there is no inscription or archive document belonging to this Ottoman Masjid, it is not known exactly by whom and when it was built. However, its architectural features suggest that the southern space and the northern space were built at different times. Considering the facts that Antalya and its environs came definitely under the rule of the Ottoman Empire in the reign of Sultan Mehmet the Conqueror; the security across Anatolia was secured after the conquest of Istanbul; the fortress settlements were abandoned in this period; and nearby plains were settled, it can be argued that the southern room was built in the time of Sultan Mehmet the Conqueror (1451-1481) at the earliest. Based on the architectural differences between the two sites, the dilatation traces seen in the southeastern and southwestern corners of the northern room, and the eighteenth-century tombstones found in the Muslim Cemetery nearby, it is thought that the northern space was added later and may have been built at the beginning of the eighteenth century at the earliest. In fact, interviews with the locals revealed that the masjid was used by their grandfathers.
