Boldt Castle on Heart Island was a project by George Boldt circa 1900 as a gift for his wife. When Mrs. Boldt died, the structure was left to decay for 70 years. The Thousand Island Bridge Authority, a government agency, now owns the property and is in the process of restoring it as it might have looked during the Gilded Age. From left to right, the visible structures are a playhouse, the main mansion, a powerhouse and a boathouse.
