Sitting where the Phoenician colony of Hadrumetum once stood nearly 3,000 years ago, the modern-day Sousse is a resort destination, especially popular with Europeans. Sometimes called "the Pearl of the Sahel" (referring to the central section of Tunisia's eastern shoreline), Sousse is prized for its excellent beaches. Arab-Islamic since the 7th century AD, the city has many fascinating attractions, like the 9th-century Great Mosque, and its medina is a UNESCO World Heritage Site.
