Alcazar de Colon

Once the home of Diego Colón, Christopher Columbus' son, this 16th century Viceregal palace (or residence of the governor/viceroy) was the nucleus of the Spanish court for more than 60 years. Inside, you'll find a museum housing an impressive collection of late medieval and Renaissance art. The house itself is also a work of art, featuring Moorish, Gothic and Renaissance touches. "This is awesome," says one on Yahoo! Travel. "With its astounding stain glass windows it is decorated with great color." One visitor tells TripAdvisor "the building itself is situated in a convenient location and has wonderful views form the balconies."

Located along Calle Las Damas in the Zona Colonial, Alcázar de Colón is open every day from 9 a.m. to 5 p.m. You'll have to pay 20 Dominican pesos (or approximately $.53 USD) to enter. Visit the palace and museum's official website for more information.
