Predjama Castle

Over 700 years old, this incredible castle is unique in every way. Home to the infamous rebel knight Erazem of Predjama in the 15th century, this Renaissance castle sits in the mouth of a cave on a 123 meter (40 foot) high cliff. The interior houses an incredible collection of historical artifacts, from antique armaments to old artworks, as well as the original furnishings and decorations. 

For the adventurous visitor, the famous tunnel of Erazem, the secret passage used when the castle was besieged, is designed as a historical center of the legend, and can be ascended. 

The observation post perched on a cliff provides a breathtaking view of the countryside, and is not to be missed. If you're visiting in July, be sure to check out the annual Erasmus tournament, in which people gather in costumes to participate in traditional tournament events in true medieval fashion. 

Practical Info

The castle is located 10 km (6 mi) from the Postojna caves, and can be accessed by shuttle, car, or bus from Ljubljana. 

The opening hours change depending upon the month, and during the summer months, the cave below the castle is open to the public.
