The Ancient City of Ephesus is an ancient Greek city near the present-day town of Selçuk on the Ionian coast. Today its ruins are a popular tourist destination, and visitors can see the ancient Library of Celsus, an amphitheater, temples, and many other buildings. Many myths and legends surround Ephesus, which was one of the key sites in early Christianity, including a house reputed to have belonged to the Virgin Mary. The site isn’t too busy, but it’s best visited with a guide who can show you the path through the ruins and point out everything there is to see.
