Discover the world famous Boldt Castle on Heart Island, an eternal monument to the memory of one man’s love for his wife. Observe the Gothic architecture of Singer Castle on Dark Island. Enjoy Panoramic Views of the 1000 Islands, and the smallest international bridge on Zavikon Island. Relax as we navigate through narrow channels and have a chance to pass 700 foot freighters in the American Shipping Channel.
Boldt Castle and Singer Castle, two iconic landmarks in the 1000 Islands, offer a glimpse into the region’s rich history and charm. Boldt Castle on Heart Island is a grand tribute to love, built by George C. Boldt for his wife, while Singer Castle on Dark Island boasts medieval-inspired design, secret passageways, and ties to the Singer Sewing Machine Company. Both castles provide a glimpse of the gilded age of the St. Lawrence River and unforgettable experiences for visitors.
