Boldt Castle


This six-story, 120-room mansion was modeled after a Rhineland castle. George C. Boldt began building it on Heart Island at the turn of the century as a gift to his wife. When she died before its completion, all work stopped and it has since then stood as an unfinished monument dedicated to her. Spend an afternoon touring the castle's draw bridge, towers, garden terraces, and gazebo. Picnic grounds and a concession area make the popular landmark very visitor-friendly. Heart Island is accessible by water shuttles that leave every 30 minutes from Alexandria Bay, New York. Tours originating in Ontario, Canada, depart from Rockport, Gananque, and Ivy Lea. Castle admission is US$6.50 for adults, US$4 for children. Hours vary by month. Call 800-847-5263 for more information.
