Located on the extreme northwestern rim of the African continent, just across the Strait of Gibraltar from Spain's southern tip, Morocco's strategic location has led to a vibrant culture. The influences of traders, invaders, and settlers that were attracted to the region have shaped Morocco's history and society. Morocco's cities are world famous for their distinctive and alluring atmospheres. The northern port of Tangier, the metropolis of Casablanca, the cultural center of Marrakech, the ancient city of Fès, and the nation's capital of Rabat reflect unique mixtures of Islamic, Berber, and European heritage.
