The castle of Don Diego Colón, built in 1517, was the home to generations of the Christopher Columbus family. The Renaissance-style structure, with its balustrade and double row of arches, has strong Moorish, Gothic, and Isabelline influences. The 22 rooms are furnished in a style to which the viceroy of the island would have been accustomed—right down to the dishes and the vice regal shaving mug. The mansion's 40-inch-thick coral-limestone walls make air-conditioning impossible. Bilingual guides are on hand for tours peppered with fascinating anecdotes, like weddings once-upon-a time.
