The Spanish Revival-style mansion was built in the 1930s for the makers of Don Q rum. One-hour tours offer glimpses into life in Ponce when rum was king. Furnishings throughout the house are grand, especially the medieval-style table and chairs in the dining room. Don't miss the chance to explore the castle—the views of the city and the sea are spectacular, too. Open Tuesday-Thursday 9:30 am-5 pm and Friday-Sunday 9:30 am-5:30 pm. Closed Mondays. US$6 adults, US$3 children and seniors. 17 El Vigia, Ponce. Phone 787-259-1774. Toll-free 800-981-2275. http://www.castilloserralles.org.
