Ephesus was an ancient Greek city on the coast of Ionia. It is in İzmir Province, Turkey. It was built in the 10th century BC on the site of the former Arzawan capital by Attic and Ionian Greek colonists.

The first Christian community in Ephesus was established by St John and developed by St Paul. Paul came in to the city to fulfill the promise that he had given on his brief visit when returning from Corinth and stayed for about three and a half years and also wrote his letters to Ephesians in captivity most probably here in Ephesus. When Paul came to Ephesus, first in the synagogues and then everywhere in the city, he preached the gospel and gained followers. The church of Ephesus which became the head of the Seven Churches in western Asia Minor was established by Paul.
