added by archaeologs Roman port on the north African coast in Libya, remarkable for its extensive imperial Roman remains. Originally settled by the Phoenicians in the 5th century BC, Sabratha was one of the three cities of Roman Tripolitania. Together with neighboring Oea and Leptis Magna, it made up a trio of wealthy trading cities, the 'Tripolis', which were important in linking the Mediterranean sea-routes to the trans-Saharan caravans. It was first annexed by Rome in 46 BC, and subsequently granted colonia status in the 2nd century AD. The city enjoyed great prosperity under the early empire. Sacked by the Austuriani in about 363, Sabratha recovered to have a second period of prosperity under Byzantine rule, when new walls were constructed enclosing a smaller area. Urban occupation seems to have been abandoned after Arab seizure in 643. Among the surviving buildings are the various bath buildings and the Antonine-period theater.
