Dougga or Thugga is a Roman ruin in northern Tunisia located on a 65 hectare site.
Dougga was originally a fortified Berber village (the name Thugga meant "pastures"). Later, it served as the seat of the Numidian king Masinissa in the 2nd century BC. The Romans occupied the city in the late 2nd century BC.
Dougga declined under Byzantine, then Vandal, occupation. Because impressive Roman ruins remain, Dougga was designated a UNESCO World Heritage Site in 1997.
A well-preserved theater was built around 168 AD, it is in such good condition until recently that it is used to stage concerts during the Dougga Festival held every summer.
