Let’s face it—Europe has no shortage of castles. From the ultra-famous Neuschwanstein in Germany to France’s Loire Valley showstoppers, they’re majestic, historic… and often swarmed with tourists and selfie sticks. But tucked away in quiet hills, deep forests, and sleepy towns are castles that have somehow slipped under the radar—no influencer queues, no gift shops, and best of all, no entrance fees.
If you’ve ever dreamed of having a medieval tower all to yourself—or at least without a crowd—this list is for you. Here are 10 hidden castles across Europe you probably haven’t heard of, but should absolutely add to your travel wish list.
1. Burg Eltz, Germany
Some Germans know about it—but most visitors skip it. Burg Eltz is tucked into the forest above the Moselle River and looks like it came straight out of a fantasy novel. It’s been family-owned for over 850 years and remarkably well preserved.
A scenic hike or shuttle ride through the woods keeps big bus tours away. Inside, you’ll find original furniture, armor, and tapestries still decorating the halls.
2. Castelul Corvinilor, Romania
Also called Corvin Castle or Hunyadi Castle, this Gothic-Renaissance fortress in Transylvania is often overshadowed by Bran Castle (“Dracula’s Castle”). But Corvin is the real deal—drawbridges, turrets, and moody medieval grandeur.
Built on a cliff, it’s dramatic, inexpensive to visit, and far less crowded. You might have entire halls to yourself.
3. Predjama Castle, Slovenia
Built into the mouth of a cave, Predjama looks like something from a fantasy movie. Perched 400 feet up a cliff, it has secret tunnels that connect to the caves below.
It’s less than an hour from Ljubljana but skipped by most tourists. Combine it with a visit to the nearby Postojna Caves for an unforgettable day trip.
4. Château de Commarque, France
Tucked into the forests of the Dordogne Valley, this semi-ruined castle feels frozen in time. You hike in, climb towers, and explore ruins without crowds or noise.
It’s moody, romantic, and perfect for daydreaming about knights and lost centuries.
5. Spiš Castle, Slovakia
One of Central Europe’s largest castle ruins, Spiš sprawls across a hilltop in eastern Slovakia. The views are unbeatable, the vibe is peaceful, and the entry fee is a bargain.
Tour buses? Not really. Just rolling hills, ruins, and quiet wonder.
6. Kreuzenstein Castle, Austria
Just outside Vienna, Kreuzenstein is a carefully reconstructed medieval castle made from pieces of other original structures. It’s been a film set more than once (like The Three Musketeers).
Despite the drama, it stays low-key with smaller crowds and surprising details.
7. Trosky Castle, Czech Republic
Two rugged towers rise from volcanic rock in the Bohemian Paradise. The ruins of Trosky Castle are full of legend and offer insane views.
Hike to the top, feel the wind, and pretend you’re guarding the realm.
8. Ardvreck Castle, Scotland
This lonely ruin by Loch Assynt in the Scottish Highlands is hauntingly beautiful. No entrance fee, no gates, no staff—just raw, historic atmosphere.
Go at dusk for ultimate mood.
9. Castillo de Loarre, Spain
In Aragon, this Romanesque castle has soaring towers and commanding views over farmland. Built in the 11th century, it’s one of Spain’s best-kept secrets.
Tour groups rarely stop here, so enjoy the quiet.
10. Kokkinos Pyrgos Castle, Crete, Greece
Less castle, more crumbled history—but with massive views over southern Crete. No signs, no tickets, no tourists.
Just climb, sit, and let time slow down.
