Predjama Castle

What it is and why it impresses

Predjama Castle is wedged into the mouth of a cave, halfway up a 123 m cliff, in the village of Predjama, 9 km from Postojna Cave. It has been there for more than 800 years and Guinness records it as the largest cave castle in the world.

Its most often told story is that of the knight Erazem of Predjama, who in the fifteenth century withstood the siege of an imperial army for more than a year. Legend says he used a secret passage in the cave to get supplies and go out raiding, and that he died betrayed by a servant, in the privy.

What you see inside

The visit is self-guided, through rooms and staircases: the armoury, the chapel, the kitchen and the torture chamber. In the attic, with views over the valley, there is a collection of medieval armour and weapons: spears, halberds, swords and crossbows. At the back, the castle goes into the rock and you reach the cave behind the walls, the one that gave Erazem water and a way out.

Allow about an hour. The guided tour is delivered in an app included in the ticket, in 19 languages, Spanish among them. If you prefer a handheld audio guide, it can be rented at the castle ticket office for €2.90.

Opening hours

Tickets and price

The ticket to the castle costs €24 in the online shop of Postojna park, which manages both sites. It is also sold at the ticket office opposite the castle, by card or in cash. It is better value as a package with the cave: from €49.90 for both visits. With a package, the cave goes at the booked time and you can see the castle on any day in the following 30 days. See the packages under tickets.

How to get there and park

You reach it by a local road from Postojna. In front of the castle there is paid parking, at €3 an hour. At certain times of year the park offers a shuttle bus from the cave for those with the combined ticket, at €2 return and about 20 minutes' journey, but in November 2026 its website lists it as temporarily out of service. If you have no car, at the cave ticket office they will help you order a taxi.

With children, pushchair, wheelchair or dog

Children like it: armour, weapons, the torture chamber and a cave behind the walls. But the castle has many narrow stairs: pushchairs and wheelchairs do not fit, and the park does not recommend it for people with very limited mobility. Carry the baby in a sling. Dogs cannot enter. Drones are banned throughout the surroundings, for the safety of the monument and because rare birds nest in the wall.

Combine it with

From May to September you can go down into the cave under the castle, with a torch and no electric light. For eating or sleeping facing the wall, Gostilna Požar is next to the castle ticket office and has rooms.
