Discover Predjama Castle: A Hidden Gem in Slovenia

The only thing more fairytale-like than a castle is a castle perched on a 400-meter cliff that’s built around the entrance of a natural cave. Moreover, this remarkable structure features a network of secret passageways. Predjama Castle in Slovenia offers all of this and more—and it’s open to the public year-round.

A Historical Marvel

Originally dating back to the 13th century, Predjama Castle is listed in the Guinness World Records as the “Largest Cave Castle.” The structure not only is built into the side of a cave but also sits atop the second-longest cave in Slovenia, which spans four impressive floors.

The Fortress of Noblemen

Throughout history, the castle served as a fortress for many noblemen, which is why the secret passageways played a crucial role in its defense. According to My Modern Met, the knight Erasmus of Lug (Erazem in Slovenian) was the lord of the castle in the 15th century. He was a notorious robber who sought refuge here after killing the commander of the imperial army. Consequently, the castle became his hideout, allowing him to utilize hidden passageways for procuring supplies and continuing his adventures in robbery.
