Ephesus ultimately from Hittite was an ancient Greek city the coast of Ionia, three kilometres southwest of present-day Selçuk 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. During the Classical Greek era it was one of the twelve cities of the Ionian League. The city flourished after it came under the control of the Roman Republic in 129 BC. According to estimates, Ephesus had a population of 33,600 to 56,000 people in the Roman period, making it the third largest city of Roman Asia Minor after Sardis and Alexandria Troas
Ephesus was one of the seven churches of Asia that are cited in the Book of Revelation. The Gospel of John may have been written here.The city was the site of several 5th century Christian Councils (see Council of Ephesus). It is also the site of a large gladiators’ graveyard. The ruins of Ephesus are a favourite international and local tourist attraction, partly owing to their easy access from Adnan Menderes Airport or from the cruise ship port of Kuşadası, some 30 km to the South.
