Predjama Castle was built in the thirteenth century, in Gothic-styled architecture.

However, after a siege in the sixteenth century, the exterior was reconstructed and is what you see today.

But there's more to this castle than meets the eye.

Beneath it lays the Postojna Cave Park.

The caves are accessible during May to September, and closed in the winter, so as not to disturb the hibernating local bats.

The castle has changed ownership throughout its history; however, the most famous inhabiter was Erazem Lueger.

He was a fifteenth century Robin Hood-like character who stole from the rich to give to the needy.

Today, the castle and caves are open for the public to explore and learn more about its previous colorful owners.
