Predjama Castle

A Fairytale Castle Embraced by Rock

A mere few kilometres from Postojna Cave, the Karst world offers an unforgettable experience in the fairytale world of knights. The impregnable medieval marvel has been perched in the middle of a 123-metre-high cliff for more than 800 years. Behind the largest cave castle in the world, there is a network of secret tunnels, from where the knight Erazem of Predjama would set out on his plundering expeditions. The Cave under Predjama Castle is the home of a colony of bats.

A World-Famous Cave Castle

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.

The Legend about Erazem of Predjama

The romantic legend about the rebellious knight Erazem, who withstood the imperial army's siege of the castle for over a year, is an indispensable part of the castle's story. A secret tunnel, a girl’s love and affection, and great artfulness – just about everything needed for a compelling story.

Although he was a brave and almost unbeatable knight, Erazem reportedly died while using a toilet after a betrayal by his servant.

Inspiration for Filmmakers

The Predjama Castle has been used as a filming venue for numerous documentaries and feature films. The castle has also mesmerised George R. R. Martin, author of the best-seller The Game of Thrones, and has hosted the Discovery Channel team, who found the castle to be inhabited by some ghosts.

A Knight for a Day

Take a walk through the castle's armoury, chapel, kitchen, torture chamber and discover the magic of medieval life.
