Sousseis a city in Tunisia, capital of the Sousse Governorate. Located 140 kilometres (87 miles) south of the capital Tunis, the city has 271,428 inhabitants (2014). The Phoenicians founded Hadrumetum in the 11th century BCE. The city allied itself with Rome during the Punic Wars, thereby escaping damage or ruin and entered a relatively peaceful 700-year period under the Pax Romana. In the 7th century AD Arab-Islamic armies conquered what is now Tunisia and rapidly spread Arab culture across what had been a thoroughly Romanized and Christianized landscape. Sousse is an important tourist resort. It has a hot semi-arid climate, with the seaside location moderating the climate, making it an all-season resort with hot, dry summers and warm, mild wet winters. The fine sandy beaches are backed by orchards and olive groves. A Medina, surrounded by its city walls and fortifications, is of historical interest. The Medina includes open and covered bazaars (souks). Buildings of historical interest include the ribat castle, the central mosque, and a historical museum in the Casbah with mosaics from the area's many Roman villas. The Carthaginian catacombs can be visited.
