The Best 20 Castles to Visit in Slovenia (Listed by Popularity)


Every year hundreds of tourists make their way to the cultural wonderland of Slovenia. Yet they all come back with a few dozen photos from the same three castles- Bled, Ljubljana, and Predjama. While these are definitely beautiful places to visit, Slovenia has a lot more to offer.

With over 500 exquisite castles and fortresses, each with its unique Renaissance, Baroque, and/or Medieval architecture, Slovenia has a rich cultural history. This list takes a deep dive into the 10 most popular attractions in Slovakia. And follows that up with another ten equally extraordinary, though less visited sites, for visitors willing to step even further off the beaten path.

The order of the list is based on Google search volume of each castle = popularity.

1. Predjama Castle

The breathtaking Predjama Castle draws in visitors from near and far because of its perfect harmony between the man-made and the natural. The stunning four-story Renaissance manor has been built into the face of the cave, allowing it to loom gracefully over the rocky landscape. 

Originally, its precarious position atop a rocky ledge was meant to prevent enemy access and keep its occupants safe. According to myth, its 15th-century owner Erasmus of Lueg got into a feud with the Holy Roman Emperor when he killed an army commander over an insult caused to his deceased friend. 

Visitors can learn more about the rich lineage of the castle as it passed from one royal family to another and eventually fell into the hands of the Yugoslav Communist government who converted it into a museum.

2. Bled Castle

Standing majestic over a stunning lake, Bled Castle is picture perfect. To enter the manor you walk across a drawstring bridge across a moat. If you’re looking to recreate your dream historical fantasy moment, this is definitely the dramatic entrance you need.

The history of Bled Castle dates back to 1004, with its Romanesque Tower making it the oldest monument in Slovenia. However, a severe earthquake hit the original fortress, and huge portions had to be rebuilt to fix the damage. Most of the Renaissance-style castle you see today was constructed after 1511.

Bled Castle hosts numerous cultural events for visitors, as well as exhibitions in the Tower which has been converted into a gallery. You can also visit the Museum or the Gothic Chapel that speak to the manor’s ancient past.

The 15th-century castle was erected over an original 11th-century defense fortress, which had served as the headquarters of the lords of Carniola during the 14th century. Most of the structures on-site today were added in the 16th and 17th centuries. The castle remained in use throughout its existence, and today it is a gorgeous venue for various events open to the public to attend.

The museum gives visitors insights to Slovenia’s history and heritage; beyond the layered past of Ljubljana Castle, the splendor of St George Chapel will leave you awestruck. Between the puppet shows and the dungeon tours, trust us when we say there’s something for everyone.

Unlike the other extravagant manors on this list, Krsko Castle’s exterior is relatively understated. What makes it so special is its rich history. The estate goes by many names, Rajhenburg Castle and Brestanica Castle being a few. 

In the late 19th century, French Trappist monks made Krsko Castle their home. Together, they built a community and the things they needed to live a comfortable and modest life. They were able to make and sell products like cheese, chocolate, and liquor to fund their dominion. After the Germans took over in 1941, most of the inhabitants were deported with only 15,000 out of the original 80,000 remaining. 

Now, the castle has been converted into a museum, gallery, and restaurant where visitors can enjoy their time, learn of the manor’s colorful history, and even use the monks’ traditional items.
