Catedral de Sevilla and Giralda Tower, Seville
Tel: 34 954 214 971
Concierge.com's insider take:
Its 15th-century builders said, "Let us create such a building that future generations will take us for lunatics." Today, Seville's cathedral is Europe's third-largest church, a Gothic pile topped by spires, towers, and a delicate network of buttresses. Inside, you'll find Columbus's tomb; works by Goya, Murillo, and Zurbarán; and a display of skulls. La Giralda is the single remaining minaret of the 12th-century mosque on which the cathedral was built. Climb the 300-foot tower's ramp for a superb city view.
