It is a typical Roman Basilica. It is 160 meters long, and located on the northern part of the state agora and has a nave and three-aisles. The Ionic columns in the basilica are adorned with bulls’ head figures dating to the 1st century A.D.
The basilica was used for stock exchange and commercial business. Meetings of the law courts were also held there in the basilica. It has three gates opening onto a stoa leading to the Bath of Varius. The statues of Augustus and his wife Livia were found at the east end, and now they are displayed in Ephesus Museum. So we can understand that the Basilica was rebuilt for the last time during the reign of the Emperor Agustus.It was destroyed by an earthquake in the middle of the Fourth Century AD.
