Whether you love history, architecture, or just a good adventure, Ohio’s hidden castles are worth every mile of the drive. Get ready to discover nine incredible places that feel like they belong in a fairy tale.
Squire’s Castle – Willoughby Hills, Ohio
Hidden deep inside the North Chagrin Reservation, Squire’s Castle looks like something straight out of a ghost story. Built in the late 1800s by Feargus Squire, a Standard Oil executive, it was meant to be a grand gatekeeper’s home for his estate that was never finished.
Today, only the roofless stone shell remains, draped in forest and folklore. Visitors hike the trails to find it and are often stunned by how dramatic it looks rising from the trees.
It is free to visit and endlessly photogenic.
Piatt Castle Mac-A-Cheek – West Liberty, Ohio
Piatt Castle Mac-A-Cheek is one of Ohio’s best-kept secrets, and it has been standing proudly since 1879. Built by Civil War General Abner Doble Piatt, this Norman French-style castle sits on a gentle hill in Logan County like it wandered in from a European countryside.
Inside, original family furnishings, artwork, and Civil War relics fill every room. Guided tours bring the history to life in a way that feels personal and warm.
It is still owned by the Piatt family descendants, which makes it even more special.
Landoll’s Mohican Castle – Loudonville, Ohio
Forget just looking at a castle from the outside – at Landoll’s Mohican Castle, you can actually spend the night inside one. Built by Richard Landoll starting in 1995, this hand-crafted stone castle sits on 1,100 acres of rolling Ohio woodland and operates as a luxury resort and restaurant.
Every stone was laid with incredible attention to detail, giving it an authentically medieval feel. Guests enjoy horseback riding, hiking, and candlelit dinners.
Staying here feels like stepping into another era entirely.
Glamorgan Castle – Alliance, Ohio
Standing boldly in the city of Alliance, Glamorgan Castle was built in 1904 for Colonel William Henry Morgan and is one of Ohio’s most impressive historic buildings. Modeled after a Welsh castle, it features 40 rooms, a grand staircase, and ornate woodwork that still takes visitors’ breath away.
Today the castle is used as an administrative building by Alliance City Schools, but tours are available for the public. Seeing a working school inside a real castle is a genuinely surreal and delightful experience worth having.
Ravenwood Castle – New Plymouth, Ohio
Tucked away in the Hocking Hills region, Ravenwood Castle is a medieval fantasy brought to life on 65 wooded acres. Owners Jim and Sue Maxwell built it as a themed inn where guests can stay in castle rooms, gypsy wagons, or hobbit holes hidden throughout the forest.
Medieval dinners, murder mystery weekends, and archery activities make every visit an adventure. The atmosphere is playful and theatrical, almost like living inside a tabletop game.
Kids and adults alike leave with the biggest smiles on their faces.
Loveland Castle Museum – Loveland, Ohio
Harry Andrews spent over 50 years building Loveland Castle by hand using river stones he collected himself, and the result is one of Ohio’s most heartwarming historic landmarks. He started construction in the 1920s as a project for his Boy Scout troop, calling it Chateau LaRoche.
The castle sits right beside the Little Miami River and is packed with medieval armor, weapons, and fascinating handwritten notes from Harry himself. Admission is very affordable, making it a perfect family outing.
Few places in Ohio carry this much personal devotion in their walls.
The Franklin Castle – Cleveland, Ohio
Nicknamed the most haunted house in Ohio, the Franklin Castle looms over Cleveland’s Ohio City neighborhood like a Victorian nightmare made of stone. Built in 1881 by German immigrant Hannes Tiedemann, the Romanesque mansion features turrets, gargoyles, hidden rooms, and secret passages.
Over the years, stories of tragedies and strange occurrences have kept ghost hunters and history lovers coming back. The building has changed hands many times and has been under restoration.
Even from the sidewalk, its brooding silhouette sends a noticeable chill down your spine.
Schwartz Castle – Columbus, Ohio
Sitting quietly in a Columbus neighborhood, Schwartz Castle surprises everyone who stumbles upon it. Built around 1895 by businessman Frederick Schwartz, this turreted Victorian home was designed to impress, blending Romanesque and castle-style architecture into one striking package.
It has served various purposes over the decades, including use as a fraternity house. The structure is a reminder that Ohio’s castle-building spirit was not limited to the countryside.
Spotting it on a neighborhood walk feels like discovering a secret that most Columbus residents somehow still do not know about.
The Castle Historic House Museum – Marietta, Ohio
Built in 1855, The Castle in Marietta is one of Ohio’s finest examples of Gothic Revival architecture, and stepping inside feels like flipping through a beautifully preserved history book. The mansion was home to the Nye-Putnam family and remained largely unchanged for generations, which is exactly what makes it so magical.
Original furniture, wallpaper, and family artifacts fill the rooms with a quiet intimacy. The museum hosts seasonal events and educational tours that bring the 1800s back to life.
History fans will absolutely love every corner of this extraordinary place.
