When you think of castles, your mind probably wanders to the misty hills of Scotland or the romantic valleys of France. But you don’t have to cross an ocean to step into a world of soaring turrets, grand ballrooms, and hidden gardens. All across the United States, visionaries, tycoons, and dreamers built their own versions of classic European castles, each with a unique American story.
From opulent Gilded Age palaces on the East Coast to quirky, hand-built fortresses in the West, these structures are a testament to incredible ambition and architectural fantasy. Forget the fairy tales—these 16 real-life American castles are open to the public and ready for you to explore.
East Coast American Castles
Boldt Castle (New York)
Located on Heart Island in the Thousand Islands region of New York, Boldt Castle is a monument to tragic love. Millionaire hotelier George C. Boldt began building the six-story, 120-room Rhineland-style castle in 1900 for his beloved wife, Louise. When she died suddenly in 1904, all construction was halted, and Boldt never returned to the island. For over 70 years, the castle stood as a ruin until it was acquired and restored. Today, visitors can take a ferry to the island and explore the beautifully rehabilitated rooms and the stunning grounds.
Plan Your Visit: Open daily seasonally (May–October). Admission is ~$13.50 for adults and $9.50 for children (plus ferry cost).

Scotty’s Castle (California)
Located in a remote corner of Death Valley National Park, Scotty’s Castle is a Spanish Colonial Revival villa that seems to appear like a mirage in the desert.

It gets its name from Walter “Death Valley Scotty” Scott, a gold prospector and con man who was Johnson’s unlikely friend and pretended the castle was his own. The engineering behind the oasis, including its hydroelectric power, is as impressive as the architecture.
Plan Your Visit: The castle is currently closed due to flood and fire damage. Limited “flood recovery” walking tours for ~$35 may be available seasonally until full reopening (projected for fall 2026).
