Fodor's Review

George C. Boldt, proprietor of the Waldorf-Astoria Hotel in New York, began building this 120-room Rhineland-style castle on Heart Island for his wife, Louise, in 1900. Four years later, when she died suddenly, he ceased work on the castle. The building remained deserted for 73 years, abused by vandals and weather. Since 1977, millions of dollars have been poured into restoration work. It's worth a trip to the 5-acre island to see the castle. Its fleet of wooden boats is in the Boldt Yacht House, on Wellesley Island. Uncle Sam Boat Tours runs shuttle boats between Alexandria Bay, Heart Island, and Wellesley Island.
