The ancient city of Ephesus, located near the Aegean Sea, was one of the biggest cities of the Greeks in Anatolia and home to the Temple of Artemis, one of the Seven Wonders of the Ancient World. The ruins of Ephesus are a major tourist attraction as well as being a sacred site in Christianity due to its association with several biblical figures, including St. Paul, St. John the Evangelist and the Virgin Mary. Ephesus is also one of the seven churches of Revelation. In the Roman period, Ephesus had a population of more than 250,000 in the 1st century BC, which served to make it one of the largest cities in the Mediterranean world.
Ephesus has always been a “center” during its date. It was once a trade center in the ancient world , a religious center in the early Christianity and today, a unique tourism center welcoming its guests from all over the world.
Pergamon or Pergamum was once a very important Greek Ancient city with a population about 70.000 people which makes the ancient city as big as Ephesus Ancient City. Pergamon existed at least from the 5th century BC, but it became important after 3rd century BC with the administration of Attalid Dynasty.
