It was originally a steep-sloped amphitheater with a three-story stone front wall and a wooden roof made of expensive, cedar of Lebanon timber. It was used as a venue for music concerts with a capacity of 5,000. It lasted intact until it was destroyed and turned into a ruin by the Heruli in 267 AD.
