Adana's oldest mosque began as the Surp Hagop Armenian church in the 13th century and was converted to a mosque in 1380, with a minaret added in 1525 and a madrasa in 1558. It takes its name, the Oil Mosque, from a 19th-century oil market once held by its gate. The building preserves layers of the city's Armenian, Ramazanoğlu and Ottoman heritage in a single courtyard complex.
Yağ Camii (Oil Mosque) is the oldest mosque in Adana and one of the most historically layered religious buildings in the region, its walls enclosing more than six centuries of continuous use. The structure began as the Surp Hagop (Saint James) Armenian church, built during the 13th-century Armenian Cilician period, and was converted to a mosque by the Ramazanoğlu beylik in 1380. A slender minaret was added in 1525 and a two-storey madrasa in 1558, creating the distinctive courtyard complex that visitors see today. The name Oil Mosque derives from a 19th-century oil market once held at the mosque's main gateway — an echo of the commercial bazaar life that still surrounds the building in Adana's Seyhan district. Inside, traces of the original Armenian church survive: the prayer hall retains a basilical orientation, and some original stone column shafts with Byzantine-style capitals support the arched ceiling. The exterior stonework reveals each successive building phase to a careful eye — the original church masonry, the Ramazanoğlu conversion work and Ottoman additions are all legible in different stone colours and dressing styles. The attached 1558 madrasa courtyard, entered through a low arched gateway, is usually quiet even when the surrounding bazaar lanes are busy, and its carved stonework exemplifies early Ottoman educational architecture in the region. A visit of 15 to 30 minutes covers the exterior, prayer hall and madrasa court. Yağ Camii is within five minutes' walk of the Büyük Saat Kulesi and makes a natural addition to an old-town circuit in Adana.

Tips for visiting
- Study the exterior stone coursework: colour and texture differences mark each construction phase from the 13th to the 16th century
- Visit mid-morning between prayer times, as the mosque is an active place of worship and access is restricted during prayers
- Modest dress is required; women should cover their hair before entering the prayer hall
- Pass through the madrasa gateway on the north side of the complex — the smaller courtyard with early Ottoman stonework is easily missed
When to visit
Mid-morning on weekdays provides the best access between prayers and the quietest atmosphere in the surrounding bazaar. The stone exterior is well lit throughout the morning from the east.
Accessibility
The mosque courtyard and prayer hall are accessible at ground level with no significant steps at the main entrance. The madrasa courtyard involves a low threshold step at the gateway. The surrounding bazaar lanes are narrow and cobbled but navigable on foot.
Frequently asked questions
Why is it called the Oil Mosque?
The name comes from a 19th-century oil market (yağ pazarı) that operated at the mosque's main gateway; the market is long gone but the popular name has remained ever since.
Can visitors enter the prayer hall?
Yes, outside the five daily prayer times and with appropriate modest dress. The hall is an active place of worship, so visitors should enter quietly.
How does it compare to the Ulu Cami?
The Yağ Camii is smaller and architecturally plainer than the Ulu Cami but is more historically eclectic, preserving physical evidence of Armenian church construction and Byzantine architectural elements absent from the later Ulu Cami.
