Church of St Peter

The Church of Saint Peter (Aramaic: Knisset Mar Semaan Kefa, Turkish: Senpiyer Kilisesi, St. Peter's Cave Church, Cave-Church of St. Peter) near Antakya (Antioch), Turkey, is composed of a cave carved into the mountainside on Mount Starius with a depth of 13 m (42 ft.), a width of 9.5 m (31 ft.) and a height of 7 m (23 ft). This cave, which some believe was used by the very first Christians, is one of Christianity's oldest churches.

It is believed by some that the founding of the church in Antioch can be traced to the Bible's Acts of the Apostles (11:25-27) where it is related that Barnabas travelled to Tarsus to bring Paul the Apostle there. They worked for one year with the nascent Christian community, and there the converts were called Christians for the first time in history. Christian tradition considers Peter, the first Apostle, as the founder of the church of Antioch, and the first priest of the Christian population that was established there; the Church of St. Peter is regarded by tradition as on the spot where he first preached the Gospel in Antioch.

The oldest surviving parts of the church building date from at least the 4th or 5th century. These include some pieces of floor mosaics, and traces of frescoes on the right side of the altar. It is thought that the tunnel inside which opens to the mountain side served the Christians to evacuate the church in case of sudden raids and attacks. Water that seeps from the nearby rocks was gathered inside for drinking purposes, and was also used for baptisms. The collection of water, which visitors drank and collected to give to those who were ill (with the belief that it was healing and curative), has lessened as a result of recent earthquakes.
