Boldt Castle, located on Heart Island in the Thousand Islands region of New York State, is a majestic castle with a romantic and tragic history. The castle was built by George Boldt, a millionaire hotel magnate, as a tribute to his beloved wife, Louise.

History of Boldt Castle
In 1900, George Boldt began constructing the castle as a grand gesture of love for his wife. The castle’s design was inspired by European castles, specifically those along the Rhine River in Germany. Boldt hired the renowned architectural firm G.W. & W.D. Hewitt to design the castle, which would feature 120 rooms, including a grand staircase, beautiful stained glass, and intricate woodwork ¹ ².
The construction of Boldt Castle was a massive undertaking, involving over 300 workers, including stonemasons, carpenters, and artists. The castle’s design was meant to be a testament to Boldt’s love for his wife, with many features incorporating hearts, including the island’s shape, which was blasted to resemble a heart.
The Tragic Story Behind the Unfinished Castle

Tragically, Louise Boldt passed away suddenly in January 1904, just months before the castle’s planned completion. George Boldt was devastated by her death and immediately stopped all construction on the castle. He never returned to Heart Island, leaving the castle abandoned for over 70 years. The castle and its surrounding structures were left to the mercy of the wind, rain, ice, snow, and vandals, causing significant damage.
Restoration and Current State

In 1977, the Thousand Islands Bridge Authority acquired Heart Island and the nearby yacht house for $1, with the agreement that all revenue generated from the castle’s operation would be directed towards restoration. Since then, over $50 million has been spent on restoring and rehabilitating the castle and its surrounding structures. Today, visitors can explore the castle’s grand halls, lush gardens, and hidden nooks, each filled with the echoes of a love story that transcends time ² ¹.
