Málaga is a port city on southern Spain’s Costa del Sol, known for its high-rise hotels and resorts jutting up from yellow-sand beaches. Looming over that modern skyline are the city’s 2 massive hilltop citadels, the Alcazaba and ruined Gibralfaro, remnants of Moorish rule. The city's soaring Renaissance cathedral is nicknamed La Manquita, one-armed lady, because one of its towers was curiously left unbuilt.
