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. A castle rivaling those of Europe, built 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… The Thousand Islands Bridge Authority (TIBA), who owns and operates Boldt Castle and the Boldt Yacht House, invite you to explore our website. Here you can glimpse what awaits you at Heart Island. A chance to experience the Boldt’s tragic love story and the magnificence of a bygone era…
