Boldt Castle, Châteauesque residence on Heart Island, Alexandria Bay, New York.
The six-story stone castle features European architectural elements with multiple towers, arched windows, and detailed ornamental designs throughout its exterior.
George Boldt, proprietor of the Waldorf-Astoria Hotel, ordered construction in 1900 but ceased all work in 1904 after his wife Louise's death.
The castle represents the architectural preferences of American millionaires during the Gilded Age, combining European castle designs with modern amenities.
Visitors access Heart Island via boat services from Alexandria Bay or Clayton between May and October, with tours available of restored interior spaces.
The Power House contains original steam engines and generators that supplied electricity to the entire island complex in the early 1900s.

These castles are located away from the main tourist destinations and represent different periods of European and American architecture. From medieval fortresses to royal residences, each castle tells its own story. The buildings occupy distinctive locations: on islands, in mountain caves, or surrounded by vineyards. The collection includes structures from various centuries that have remained relatively unknown due to their remote locations or historical circumstances. Some of these castles served as defensive strongholds, while others functioned as aristocratic homes or administrative centers. These sites offer visitors the opportunity to experience historical architecture in quiet settings and learn about the regional characteristics of different countries and periods.
These North American mansions display the architecture and life of the industrial elite from the 19th and early 20th centuries. From Frank Lloyd Wright's Fallingwater to the Vanderbilt estate The Breakers, these buildings present various architectural styles including French Renaissance, Tudor and Victorian design.
