Predjama Castle: A Fortress Built into the Cliff
Predjama Castle is one of Slovenia’s most iconic castles, famous for its unique position built directly into the mouth of a towering cliff. Located just a short drive from Postojna Cave, this 13th-century castle is as fascinating as it is scenic. It was the stronghold of the legendary knight Erazem Lueger, who became a Robin Hood-like figure in Slovenian folklore. The castle’s extensive underground tunnel system allowed him to escape sieges and supply himself secretly.
Inside, visitors can explore rooms furnished with medieval artifacts, learn about Erazem’s daring escapades, and discover hidden passages within the rock walls. The view of the castle from below, nestled into the limestone cliff with green forests surrounding it, is simply unforgettable.
Ljubljana Castle: The Capital’s Crowning Jewel
Overlooking the city of Ljubljana from Castle Hill, Ljubljana Castle is a must-visit for anyone in the capital. Originally a medieval fortress, it has been restored over the years to include historical exhibitions, cultural events, and a fantastic viewing tower offering panoramic views of the city and Julian Alps.
You can reach the castle via a scenic hike, or opt for the funicular that takes you directly to the top. Once there, explore the castle museum, which provides insight into Slovenia’s history and cultural heritage, or visit the prison exhibit and chapel. In summer, the castle hosts open-air concerts and film screenings, making it a lively place to experience both history and local culture.
Bled Castle: A Fairytale Fortress Above the Lake
Perched atop a steep cliff overlooking Lake Bled, Bled Castle is perhaps Slovenia’s most romantic castle. The views from the castle’s terraces are breathtaking, with Lake Bled’s iconic island, the surrounding Julian Alps, and the rolling hills in the distance. Dating back to the 11th century, Bled Castle is the oldest castle in Slovenia, and its grounds are filled with interesting attractions.
Inside, visitors can explore a medieval printing workshop, a wine cellar where you can bottle your own wine, and a small museum covering Bled’s local history. The castle restaurant offers traditional Slovenian dishes with stunning lake views, making it a memorable stop for both its scenery and sense of history.

Other castles to visit:
Celje Castle: A Legacy of the Counts of Celje
Celje Castle, also known as Stari Grad, is the largest medieval fortress in Slovenia and offers an exciting journey back in time. Built by the Counts of Celje, a powerful noble family, this fortress once played a crucial role in the region’s politics and defense. Today, the partially restored ruins provide a glimpse into its past splendour, with sweeping views over the Savinja Valley.
The castle hosts various medieval-themed events, including knights’ tournaments and historical reenactments, bringing its rich history to life. As you wander the castle grounds, you can almost imagine the Counts of Celje themselves once pacing the same pathways.
Otočec Castle: Slovenia’s Only Water Castle
Otočec Castle is unique among Slovenian castles, as it’s the only one built on an island in the middle of a river. Located on a small island in the Krka River, this 13th-century castle has been beautifully restored and transformed into a luxury hotel, making it a romantic destination for couples. Surrounded by lush greenery, the castle offers a serene escape with a touch of luxury.
Guests can stay overnight or enjoy a meal at the castle’s renowned restaurant, which serves fine Slovenian cuisine with a modern twist. For those not staying the night, walking the grounds and enjoying the castle’s peaceful riverside setting is well worth the trip.
Snežnik Castle: A Hidden Gem in a Forest
Tucked away in a forested area near the Croatian border, Snežnik Castle is one of Slovenia’s best-preserved castles and feels like a step into a fairytale. Unlike many Slovenian castles that lie in ruins, Snežnik has retained its 19th-century appearance, complete with period furnishings, paintings, and even personal items that belonged to its former residents.
The castle is surrounded by a peaceful forest and a lake, creating a picturesque setting for a visit. Inside, a guided tour provides insight into the life of the aristocracy in the 1800s, with rooms filled with original furniture, hunting trophies, and grand hallways. For a tranquil and lesser-known castle experience, Snežnik is a perfect choice.
