The Thousand Islands Bridge Authority (TIBA) welcomes you to tour Boldt Castle to explore and experience an attraction like no other. Construction began on Boldt Castle in 1900 at the bidding of millionaire hotel magnate George C. Boldt as a tribute to his beloved wife Louise. Boldt Castle was designed as their summer dream home on the St. Lawrence River, in the heart of the 1000 Islands. However it was not to be, Mrs. Boldt passed away suddenly just months before the completion of the castle. Mr. Boldt was inconsolable and immediately stopped all construction on Heart Island, leaving the property vacant for over seventy years. Today Boldt Castle, located near Alexandria Bay, NY in the famed 1000 Islands is once again becoming what it was always meant to be, the premier home and attraction in the region. Whether you are making an annual visit to see what’s new, looking for an affordable family vacation close to home or a couple seeking that romantic getaway, Boldt Castle and the Boldt Yacht House has something for you.Visit Canada.
