Trip Planner:   Predjama Castle

Predjama Castle, Postojna

Perched on a high, rocky cliff for over 700 years, the unconquerable four levels of Predjama Castle were built within a cave mouth. Cross a drawbridge over a rushing river and visit the restored living quarters, chapel, and dungeon to get an idea of how people once lived here. The castle's most famous resident and the subject of many legends was Erazem Lueger, a 15th-century knight who rebelled against the Austrian emperor. See his hiding place called Erazem's Nook and ascend along Erazem's Tunnel. Do not miss the 16th-century treasure chest uncovered in the cellar in 1991. An observation post offers a panoramic view of the surrounding landscape. The castle entered the Guinness Book of Records as the biggest cave castle in the world.

  • This is a great castle to visit. Must visit. World largest castle build in a cave. Amazing place. Interesting how ancient people built this castle. Of course there will be some walking and climbing inside. Do remember to pick up the audio guide machine at the entrance.
  • Amazing castle in a big cave, during the summer you could also visit the caves that served the people in the castle to walk away during attacks. Well preserved and the landscapes are awesome. A lot of stairs in there, wear comfortable shoes!
