The city's strategic location has ensured it has endured a turbulent history, often being used as a trade and military outpost. Originally an old Carthaginian colony, it has since been held by the Romans, Vandals, Byzantines, and Arabs, and has been known as 'Abyla', 'Septem' and 'Cibta'. It was finally taken over by Spain in 1580 and has remained Spanish since then, with the name 'Ceuta'. Covering an area of just ten square miles, the enclave is dominated by the hill of Monte Hacho, sometimes believed to be the legendary Pillars of Hercules. With a fascinating mix of both Spanish and African influences and surrounded by massive 14th-century city walls, Ceuta has a charm and grandeur all of its own. As an autonomous region of Spain, Ceuta is part of the territory of the EU, but is considered a special low-tax zone. Leather goods, ceramics and embroidery are common purchases from the city.
