Anatolia is a symbol of the brotherhood of religions where diverse religions and cultures have coexisted in peace over centuries. The Hatay Province hosts one of the prominent cities reflecting that feature of Anatolia. The provincial seat Antakya (ancient Antioch) is regarded a centre of faith and the city of brotherhood of religions because the shrines of Muslim, Christian and Jewish faiths stand side by side or in a close proximity. The holiest structure for the city's Christians, the Cave Church of Saint Peter, regarded as 'the first church of the world', is also here. The church was established in a natural cave of 13 metres wide and 7 metres high, and it is believed to be used by Saint Peter, the Preeminent Apostle and the first pope to spread the message of Jesus Christ. Another aspect of importance for Christianity is the fact that the name Christian was first given here to those who believe in Jesus Christ. The Church of St. Peter was inscribed in the Tentative List of UNESCO World Heritage in 2011.
