Iconic Castles and Their Grand Stories

The Thousand Islands are not just a haven for nature lovers; they are also home to magnificent castles, each with a rich history and captivating tales that transport visitors back in time. This section will guide you through two of the most famous, Boldt Castle and Singer Castle, detailing their significance and how to experience their grandeur firsthand.

Boldt Castle: A Poignant Testament of Love on Heart Island

Perhaps the most famous landmark in the Thousand Islands, Boldt Castle on Heart Island is an unfinished architectural masterpiece with a deeply moving story. Built by hotel magnate George C. Boldt as a grand tribute to his beloved wife, Louise, construction began in 1900. However, tragedy struck in 1904 when Louise unexpectedly passed away, prompting a heartbroken Boldt to cease all work on the castle. He never returned to Heart Island.

Today, managed by the Thousand Islands Bridge Authority, the castle has been lovingly restored and partially completed, allowing visitors to delve into its poignant history. You can explore the elaborate rooms, walk through hidden tunnels, and wander the beautifully manicured grounds, which include the Alster Tower and the Power House. The castle boasts over 120 rooms, showcasing Gilded Age luxury and the ambitious vision of its creator.

To access Heart Island and Boldt Castle, visitors typically embark on dedicated boat tours from Alexandria Bay or Clayton, New York. These scenic cruises offer stunning views of the St. Lawrence River as you approach the iconic heart-shaped island. Do remember that as Heart Island is located within the United States, international visitors will pass through U.S. Customs and Border Protection upon arrival.

Singer Castle: Mystery and Grandeur on Dark Island

Just a short distance away, nestled mysteriously on Dark Island, lies Singer Castle—a unique Rhineland-style fortress that seems straight out of a European fairy tale. Completed in 1905 for Frederick G. Bourne, president of the Singer Sewing Machine Company, this granite edifice is renowned for its intricate design and captivating secrets, including a network of secret passages that once allowed staff to move unseen throughout the structure.

Singer Castle offers a fascinating glimpse into the opulent lifestyle of early 20th-century industrialists. It stands as one of the few castles in New York State and the only authentic Rhineland-style castle in the United States. During your visit, you’ll uncover its fascinating history and discover the intricate details of its 28 rooms, including a dungeon, a two-story library, and a grand dining hall.

Singer Castle is often included as a stop on extended boat tours of the Thousand Islands, offering a truly immersive experience of the region's rich heritage. While Boldt Castle is the heart-wrenching tale of love, Singer Castle captivates with its mystery and architectural uniqueness.

Beyond the historical grandeur of its iconic castles, the Thousand Islands region truly comes alive when experienced from the shimmering waters that define it.

It is the lifeblood of the region, offering endless opportunities for aquatic adventure and exploration, from thrilling boat tours to serene paddling and world-class fishing.
