The Amphitheatre of Durrës was built on the hillside inside the city walls in the early 2nd century AD. In its prime it had the capacity to seat 15,000 to 20,000 spectators, but these days a few inhabited houses occupy the stage, a reminder of its recent rediscovery (in 1966) and excavation. The Byzantine chapel in the amphitheatre has several beautiful mosaics. There are knowledgable English-speaking guides on site daily until 3pm; they work on a tipping basis.
