Why Travel to Slovenia?
Slovenia has for a long time been one of Europe’s best kept secrets – there’s truly something for everything here. On my last visit to Slovenia, I had the immense pleasure of doing a variety of different activities, including hiking, boating, road tripping, eating, and exploring some fascinating historic buildings and castles. With its fascinating history and incredible nature, Slovenia is a treat for the senses and a hidden gem waiting to be explored.
How Many Castles Are in Slovenia?
After spending some time traveling around Slovenia, you might start to feel like there are churches and castles around every turn. And, in many respects, that’s actually true! In total, there are over 500 castles in Slovenia, many of which have been converted into museums and parks. That’s a lot – approximately one castle per 15 miles – for a country as tiny as Slovenia!
While some of these castles are in impeccable condition, others are now standing as ruins you can explore. Either way, they’re all magical in their own way. In this post, we’ll cover 25 of the most beautiful castles in Slovenia that look like they came from a fairytale.
Getting Around Slovenia
After reading this article, you might ask yourself how you can even visit many of these castles. Although it’s probably not the cheapest option, the easiest answer is to rent a car. Driving in Slovenia is fairly easy thanks to mostly well-paved highways and roads, but it does get a little tricky in the small towns, where the streets are narrow and typically only fit one lane of cars. However, I highly recommend renting a car as it will give you the flexibility to travel around at your own pace.
Castles in Ljubljana & Central Slovenia
1. Ljubljana Castle
One of the most popular and iconic castles in Slovenia is located right in the middle of its capital city, Ljubljana. Situated on top of a hill, Ljubljana Castle is a citadel that has overlooked the city for over 900 years. While you can take a funicular car to the top, I recommend exploring some of the winding staircases and alleyways surrounding the castle, making your way up to the top by foot. Once you arrive at the castle, you can explore the castle itself, with its famous rooms, its puppet theater, and more. Afterward, take some time to explore the grounds, which boast gravel walking trails and stunning city views.

Although this castle is quite small today, it used to be just a tiny section of a much larger castle complex that was constructed in the 11th or 12th century. Visitors cannot enter the castle’s chapel without a guide, which can only be organized by appointment. However, this magical structure is lovely even just to look at and photograph!

Built in the 16th century as a hall to store food for the residents of Idrija, a large mining city. It was owned by the mining administration and housed a few mine worker residents.

In the 18th century, it was abandoned and left to ruin, its remains used to built the rest of the town. Today, it still has a few structural pieces intact, like a small turret-like building, but most of it is simply brick walls now. Visitors can walk the grounds and explore this magical ruin.

9. Pilgrimage Church of the Assumption of Maria (Bled Island)
OK, OK, I know this isn’t a castle. But it’s too beautiful and too iconic to leave off a list like this, especially because of how fairytale-esque it is. When people think of Slovenia, they often think of this very image, the beautiful tiny church on the island in the middle of Lake Bled. Well, folks, the Church of the Assumption of Maria is it. Aside from being one of Slovenia’s most iconic views, the Pilgrimage Church has a really fascinating history, too. According to the legends, if you ring the bell three times at the church, your wishes will come true. Or, go for a hike to the Ojstrica viewpoint to see a picture-perfect view of its iconic steeple.

12. Kacenstajn Castle
At first glance, Kacenstajn Castle looks like another one of Slovenia’s beautiful baroque castles, but it has quite a dark history. During WWII, it served as a prison, and its gruesome history led to 849 bodies of detainees being buried on the groups. Today, it serves a dual purpose – much of it is a psychiatric clinic/hospital, but it also houses a Hostage Museum open to the public.

An 800-year old beauty, this castle was built into the natural cave system in the cliff it occupies, making it a really interesting juxtaposition of man-made and natural elements.

The building boasts beautiful gray and white patterns, and looks like something out of a storybook. It houses the oldest pharmacy in all of Europe, which visitors can still tour today. It has also hosted several monks throughout history, and is now owned by the Conventual Franciscans, who operate regular masses in the monastery’s chapel.

Castles in Northeastern Slovenia
20. Betnava Castle
Constructed in the 14th century, Betnava Castle was built to model a Florentine-style mansion. With its pink exterior and white detail, it looks somewhat like a dollhouse with some dilapidated charm. This castle is interesting because it has come to ruin in recent years due to poor maintenance and abandonment. For this reason, visitors cannot enter the building. However, it isn’t hard to see, even from the outside, how beautiful this castle once was.
Address: Streliška cesta 150a, 2000 Maribor, Slovenia

24. Stari Grad Celje (Celje Castle)
Once the largest fort in Slovenia, it looks like a stereotypical “castle on a hill,” a ruin of something that was once grandiose. Fabled to be a completely impenetrable target, this castle is a remnant of the fortitude back then. The earliest records of this castle were from the 12th century, and today it sits as a ruin in the city of Celje. On a visit to the Celje area, tourists can see some of the castle’s remining interiors and explore its grounds.
