Hasanaliler Church is one of innumerable historical treasures hidden in the mountainous landscape of Cilicia Trachea ("Rugged Cilicia"). This rough mountain district is formed by the spurs of the Taurus Mountains. Among numerous valleys, deep gorges, and magnificent mountaintops, the curious traveller will find ancient cities, sanctuaries, ruined farmsteads, and churches, along the natural wonders such as deep caves and picturesque sinkholes.
Hasanaliler is the name of a small village which is now a neighbourhood of Narlıkuyu in Silifke District of Mersin Province. Its biggest tourist attraction is the Byzantine church, located next to the village mosque, just by the road leading inland from the Cennet and Cehennem (Heaven and Hell) sinkholes, around 4 kilometres from the Mediterranean coast.
The church is a heavily damaged 6th-century Byzantine basilica-type building. The narthex of the three-nave church is to the west of the building, while the church entrance is in the north.
There is a cistern under the building and an engraving on the wall on the left side of the road, as well as a sarcophagus above the engraving.
