56 impressive Corinthian columns encircle this asymmetrical public plaza measuring 260 by 295 feet. Apparently the columns had Ionic capitals when this public square was built around 130 AD. They were replaced with this impressive colonnade during the 2nd century. At this time it also had two altars in the middle. Today the square is paved with large limestone blocks. The Oval Forum was the venue for social and political activities.
