Boldt Castle & Boldt Yacht House — Attraction in Town of Alexandria

Boldt Castle is a major landmark and tourist attraction in the Thousand Islands region of the U.S. state of New York. Open to guests seasonally between mid May and mid October. It is located on Heart Island in the Saint Lawrence River. Heart Island is part of the Town of Alexandria, in Jefferson County. Originally a private mansion built by American millionaire George Boldt, it is today maintained by the Thousand Islands Bridge Authorityas a tourist attraction.

George Boldt, general manager of the Waldorf-Astoria Hotel in New York City and manager of the Bellevue-Stratford Hotel in Philadelphia, and his family enjoyed an earlier frame cottage on Hart Island (the island's original name) for several summers, which they greatly expanded. In 1900, George Boldt launched an ambitious construction campaign to build a huge masonry structure, one of the largest private homes in the United States. He engaged the architectural firm G. W. & W. D. Hewitt and hundreds of workers for a six-story "castle" as a present to his wife. In addition, four other masonry structures on the island are architecturally notable.

Equally distinctive is a huge yacht house on neighboring Wellesley Island, where the Boldts had another summer home and a vast estate, incorporating farms, canals, a golf course, tennis courts, stables, and a polo field.

The construction of Boldt Castle ceased abruptly in early 1904 after the death of Boldt's wife, Louise Kehrer Boldt. Boldt never returned to Heart Island, leaving this structure as a monument of his love.

For 73 years, the castle and other stone structures were left exposed to the harsh winter weather and occasional vandals.

The Thousand Islands Bridge Authority acquired Heart Island and the nearby yacht house in 1977, for one dollar, under the agreement that all revenues obtained from the castle operation would be applied towards restoration, so that the island would be preserved for the enjoyment of future generations.

In the two decades after acquiring the property, the Thousand Islands Bridge Authority spent some $15 million for restoration and improvements here, and work continues annually.

The initial goal of the restoration of Heart Island was not to finish what had not been completed, but to restore the island to the state it was in when construction was halted.

Improvements have gone beyond that stage, however; a stained glass dome, marble floor, and grand staircase woodwork, for instance, now seen in the main hall, were not original but are modern...

⭐⭐⭐⭐⭐ Boldt Castle: A Stunning Blend of Craftsmanship, History, and Beauty

@boldtcastle- I finally made it to Boldt Castle after waiting since 2020, and WOW, it did not disappoint! 🏰 Located on Heart Island in the Thousand Islands, NY- this place is a true masterpiece of craftsmanship and history.

First, let me tell you a bit about Heart Island—it’s literally shaped like a heart! ❤️ George Boldt had it reshaped to reflect his love for his wife, Louise, and the symbolism runs deep throughout the estate. But this castle isn’t just about grand gestures—it’s about the artisans and craftspeople who brought it to life. 🛠️ Every brick, every marble tile, every carved stone has a story. These skilled hands, from the original builders in 1900 to today’s restoration teams, have made sure that Boldt Castle stands as a testament to the dedication and artistry of generations of workers. ✨

Walking through the gardens, admiring the majestic Power House and Clock Tower, and exploring the Alster Tower (aka The Playhouse), I was struck by how the island’s natural beauty blends so seamlessly with the human touch. 🌳 Did you know that the Alster Tower was built as a place for fun? 🎉 It features billiard tables, a ballroom, and even a stage where guests could let loose. It’s a playful side of the otherwise grand estate that many visitors might overlook!

... And who knew? Thousand Island Dressing 🥗 was created right here! Fun fact for you! 😍 🥗 George Boldt’s chef made it while they were cruising through the Thousand Islands, and it became a hit at his Waldorf-Astoria Hotel in New York…. A tasty piece of history!

But my favorite part? Taking the ferry 🛳️ back as the sun set over the St. Lawrence River 🌅. The reflections on the water were magical—truly the perfect way to end a day filled with history and beauty.

If you’re visiting, October 14 is the last day of the season, so make sure to check it out before it closes! You won’t regret it.

Thank you Boldt Island staff and Captains- you made a day filled with history and memories iconic and that much more!!!
