Predjama Castle

Slovenia is one of the most charming destinations in Europe, with fairytale good looks in medieval towns, the stunning snow-capped Julian Alps, turquoise rivers, sapphire lakes, and plenty of historic sites. With over half of its surface covered in forest, it’s one of the greenest countries in more ways than one. Plus, outdoor adventure abounds with opportunities to hike, bike, kayak, raft, explore on horseback, or ski, while providing a fascinating mix of Slavic, Italian, and German cultures that can be tasted in the mouthwatering cuisine.

The Predjama Castle is a beautiful renaissance castle built in the mouth of a cave in the idyllic village of Predjama, near Postojna, in the Karst region of Slovenia. It was constructed in the Gothic style in the 13th century and is considered to be one of the more significant architectural masterpieces of that time.

When to visit Predjama Castle

The castle is open to visitors year-round, whereas the cave is open only from June to August due to the bats’ hibernation period during the rest of the year. Unforgettable experiences guaranteed!

Natural elements seamlessly interwoven with manmade ones, the result of man’s work and nature’s creativity has created a pearl of medieval resourcefulness. The world’s largest cave castle, listed as one of the Guinness World Records, tells a picturesque story about the times when comfort had to give way to safety, and when the clatter of weapons would often drown out troubadours’ songs. It is so special and unique, it ranks among the ten most fascinating castles in the world, and so romantic that many couples choose it for their wedding vows.

What is the best time to visit Predjama Castle?

The castle is open to visitors year-round, whereas the cave is open only from June to August due to the bats’ hibernation period during the rest of the year.

What are the essential sites to see in Slovenia?

While the mountains and other natural attractions are a must, you won’t want to miss the sites in Ljubljana like Ljubljana Castle which has stood atop Castle Hill for over 900 years overlooking the city. Lake Bled is another top spot, including the islet at its heart that’s topped by Our Lady of the Lake Church – rent a rowboat to explore it. Predjama Castle, uniquely set within the mouth of a cave midway up a cliff, and the Skocjan Caves are two of the other not-to-be-missed highlights.

Is Slovenia worth visiting?

Despite being an under-the-radar destination, and perhaps partly because of that, Slovenia provides an unforgettable escape with great diversity. It may be small, but it has an incredible range of landscapes from stunning coast and flat plains to deep caves and the high peaks of the Alps. Visitors rave about its glacial lakes, charming medieval towns, vineyard-covered hills, and storybook castles too. From exploring history to taking part in thrilling activities like zip-lining, it offers something for everyone.
