You probably think American castles are just hotel lobbies with extra turrets. Fair. Most are either wedding venues or photo ops next to a gift shop that sells “ye olde” hot sauce.
But some? Some are weird enough, remote enough, or obsessive enough to be worth the drive. A few were built by actual eccentrics with way too much time and concrete. Others just ended up looking regal by accident.
We found the ones that make you stop, squint, and say, “Wait, who built that and why?” Not the famous ones. The fun ones.
Bishop Castle, Colorado
This isn’t just a castle, but a defiant sculpture project welded by one man over five decades. Tucked in Colorado’s San Isabel National Forest, Jim Bishop built it using salvaged metal, stone, and sheer obsession. You’ll climb narrow stairs, walk across open-air bridges, and maybe spot a dragon head made of scrap.
It’s free to enter, but drop a few bucks in the donation box if you can. Bring boots and check the weather. This place doesn’t have guardrails or safety warnings.
Boldt Castle, New York
A Love Story Left Unfinished
In the Thousand Islands region, this European-style castle rises from Heart Island like it washed in from Bavaria. George Boldt built it for his wife in the early 1900s, then stopped construction when she suddenly died. The place sat empty for decades before locals restored it.
You’ll take a ferry from Alexandria Bay and wander turrets, ballrooms, and heartbreak. Go in early fall for thinner crowds and better light for photos. Passport needed if you’re coming from Canada’s side.
Hearst Castle, California
Hollywood Royalty’s Favorite Playground
Perched above the Pacific in San Simeon, Hearst Castle mixes Roman columns with Spanish tiles and Greco gardens. William Randolph Hearst built it to host movie stars, politicians, and circus animals. The Neptune Pool alone makes the drive worth it.
Tours sell out fast in summer, so book weeks ahead. Skip the bus tour and take the evening option. Sunset from the terrace is unbeatable, and the estate feels more mysterious in the dark.
Hammond Castle, Massachusetts
Built for a Mad Inventor and His Ghosts
John Hays Hammond Jr. created this medieval-style mansion in Gloucester to house his inventions and freak out his dinner guests. It has hidden passageways, imported stone walls, and one of the creepiest pipe organs you’ll ever hear. The castle overlooks the Atlantic and opens seasonally for tours.
Don’t miss the basement, it’s packed with bizarre scientific gear. Locals say the place is haunted. If you’re into paranormal stuff, book one of the night investigations.
Iolani Palace, Hawaii
The Only Royal Palace in the U.S.
Right in the heart of Honolulu, Iolani Palace is where Hawaiian royalty ruled, resisted colonization, and were eventually overthrown. You’ll walk through throne rooms, see Queen Liliʻuokalani’s prison quilt, and hear stories that aren’t in your average textbook. It’s a powerful, emotional visit.
Entry is ticketed, and self-guided audio tours are surprisingly good. Try to catch the Royal Hawaiian Band if they’re playing on the lawn. It’s like stepping back into 1885.
Gillette Castle, Connecticut
Sherlock Holmes Meets Stone Fortress
Actor William Gillette, best known for playing Sherlock Holmes, designed this strange cliffside retreat over the Connecticut River. Inside, you’ll find trick doors, puzzle locks, and furniture he designed himself. It’s weird in the best way.
Take the ferry from Chester if you want the full cinematic arrival. Trails around the castle give you great views, especially in October when the leaves turn. Closed in winter, so check dates before planning.
Castle in the Clouds, New Hampshire
Where You Watch Fog Roll Like Magic
This mountaintop estate in Moultonborough looks like a Scottish manor landed in the White Mountains. Built in 1914, it mixes luxury with panoramic views. You’ll ride a trolley up to the castle, tour the original furnishings, and grab lunch with a view that doesn’t quit.
The real secret? Walk the Brook Walk trail nearby. Waterfalls, mossy stone bridges, and almost no tourists. Visit in late September for fall color without the chaos.
Loveland Castle, Ohio
Knightly Vibes Built by Hand
Harry Andrews was a World War I medic who came home and started laying bricks. By himself. For the next 50 years. Loveland Castle, or Château Laroche, is the result, complete with towers, swords, and armor displays.
You can tour it for just a few bucks. It’s small but loaded with odd charm. Try visiting during one of their medieval festivals when the place fills with live sword fights and fire-breathing performers.
Don’t miss the basement, it’s packed with bizarre scientific gear. Locals say the place is haunted. If you’re into paranormal stuff, book one of the night investigations.
Scotty’s Castle, California
Desert Mirage with a Twisted Tale
In the heart of Death Valley, Scotty’s Castle looks like a mirage with red tile roofs and arched courtyards. It was built with stolen money, maybe. Or maybe not. The truth still feels like gossip.
Closed for years due to flood damage, it’s finally reopening in 2025 with guided ranger tours only. Bring water, wear a hat, and check road closures before you go. The castle is remote, and summer heat is brutal.
Fonthill Castle, Pennsylvania
Concrete Dreams and Tile Obsession
You’ll never see another place like this. Fonthill Castle in Doylestown is entirely made of concrete, built by archaeologist Henry Mercer to show off his collection of tiles and artifacts. Every room, ceiling, and stairwell tells a different story.
Go on a weekday to avoid school groups. Wear soft shoes—the stairs are tight, and some ceilings are low. The nearby Mercer Museum is also worth checking out if you love weird collections.
Berkeley Castle, West Virginia
Royal Drama in a River Town
This 19th-century stone fortress overlooks the Potomac River in Berkeley Springs. Built by a railroad baron and later rumored to house royal European guests, it has thick stone walls, hidden wine cellars, and a tower with a view. It’s privately owned but opens for public tours during local festivals or by reservation.
Ask about the stained glass windows. They’re rumored to be imported from Germany. If you’re staying overnight, the nearby Country Inn has rooms with clawfoot tubs and a perfect view of the castle.
Castle Post, Kentucky
Sleep Like a Duke in Horse Country
Just outside Lexington, this place actually lets you stay the night. Castle Post (formerly Martin Castle) started as a romantic gift, sat abandoned for years, and now runs as a luxury inn. It’s got turrets, suites, and fine dining, plus horses grazing out front.
You don’t need to book a room to explore the grounds, but reservations help. Best time to go? Derby season. The castle throws watch parties with mint juleps and front-row vibes.
Squire’s Castle, Ohio
Half a Castle, Whole Vibe
Locals don’t care that it’s technically just a gatehouse. Squire’s Castle, tucked inside North Chagrin Reservation, has the look, the lawn, and the ghost stories. You’ll find families grilling out front and couples posing under ivy-covered archways. It’s free, open year-round, and super photogenic. But don’t just stop at the castle, take the trail that loops past creeks and wildflowers.
Bring snacks and bug spray. Nearby Sunset Pond is great for quiet breaks when the castle crowd gets noisy.
Montezuma Castle, Arizona
Not a Castle. Still Blows Your Mind.
Don’t expect turrets. This “castle” is a 900-year-old cliffside apartment complex carved into limestone by the Sinagua people. It clings to the rock above Camp Verde like it grew there. The park trail’s a short loop, stroller-friendly, and shaded by cottonwoods.
You can’t go inside the dwelling, but rangers will fill you in on the architecture and survival tricks. Bring water, Arizona sun hits hard even in spring. Pair it with nearby Montezuma Well for a surreal oasis that’s rarely crowded.
Lyndhurst Mansion, New York
Big Drama on the Hudson
Lyndhurst leans theatrical from the moment you see it. You’ll spot this Gothic mansion from the Metro-North train before you even arrive in Tarrytown. Inside, it’s all dark wood, tall windows, and furniture too fancy to touch. Outside, the sweeping lawn drops toward the Hudson, perfect for lazy picnics or dramatic Instagram shots.
Go during one of their seasonal festivals for food trucks and vintage cars. Best advice? Take the back path through the rose garden. It’s quieter and hits golden hour just right.
