It is one of the three main streets of Ephesus. Harbor Street starts from the theater and end at the harbor. It is 530meters long and there were shops and crosswalks on both sides. This street is also called “Arcadian” and it is about 11 meters wide. It was very close to the harbour and there was 'Four Columned Monument' at the end of the street.
On each of these columns the statues of the four Evangelists was situated. This street is also known to be lightened at nights. Holes were made on the columns in order to put torches in it. The Gymnasium takes place on the right of this main street. This was the high school of Ephesus. Next to the harbour there was a huge Roman Bath. Near the Roman Bath there is the Church of Virgin Mary, which was built as a pagan high school but converted into a Church in the 4th Century AD. It is the first church ever named after the Mother of Jesus Christ. This Church is also called Ecumenical Council Church because the 3rd Council held in this structure in 431 AD in Ephesus.
