Malaga is a port city on the Costa del Sol in southern Spain, known for its high-rise hotels and resorts that jut out from its yellow-sand beaches. On this modern profile, on two hills, rise the two enormous citadels of the city, the Alcazaba and the ruins of Gibralfaro, remnants of the Moorish regime. The city's soaring Renaissance cathedral is nicknamed La Manquita because one of its towers curiously was not finished.
