Hisar Camii is a historical mosque located in the Hisarönü neighborhood of İzmir’s Konak district, featuring architectural characteristics of the Ottoman period. Although there are differing views regarding its construction, the generally accepted view is that the mosque was built or converted from a Latin church in the late 16th century by a benefactor named Molla Yakup. The mosque derives its name from its proximity to the hisar (fortress) at the mouth of the harbor and has undergone various repairs and interventions over time.

Sources present varying claims regarding the construction date and origins of Hisar Camii. Some indicate that the mosque was built by Molla Yakup in 1591–92 or 1597–98, while other historical accounts suggest it was converted from a Latin church. Additionally, Evliya Çelebi’s Seyahatname mentions that the mosque was constructed in the year 1000 AH (1591–92).【1】
Throughout its history, Hisar Camii has been repaired multiple times following earthquakes and other events in the 19th century. After earthquakes in 1813, 1868, and 1881, parts of the mosque, including its congregational area, were altered during restoration efforts. Furthermore, its minaret was reconstructed in 1927.【2】
Hisar Camii is a square-plan structure built using cut stone and rubble stone. The central dome rests on eight piers and is surrounded by six smaller domes. Access to the prayer hall from the western congregational area is provided through three doorways. The congregational area is covered by domes supported by marble columns and arches.
The pulpit inside the mosque is made of wood and inlaid with mother-of-pearl, while the mihrab is a circular niche. The interior decorations include penwork ornamentation dated to the 18th and 19th centuries. The minaret is a single-balconied structure with a circular shaft; it was renovated in 1927.
