Boldt Castle

Nestled in the heart of Heart Island, Boldt Castle stands as a testament to early 20th-century opulence and romance. George Boldt initiated the construction of this 120-room castle in 1900 as a grand gesture for his wife, though it remained unfinished until 1977 when it was finally completed and opened to the public. Today, visitors can explore the castle’s intricate architecture and expansive grounds, offering a glimpse into the Gilded Age. The castle’s location in the Thousand Islands of the Saint Lawrence River adds to its allure, providing a scenic backdrop that enhances the historical experience.
