But this - despite the fact that he was very small - the most unique. Perhaps he only made entirely inside the cave - the second largest cave in Slovenia.
The castle is located 9 kilometers from Postojna (not far from this place and is the biggest cave in the world - famous Postojna Jama).
The name of the castle "Predjama Castle" means "castle in front of the cave." Village located near the castle, called Predyamoy.
The earliest records of the castle date back to the XIII century. But there is speculation that he began to build in the first half of the XII century. Completely construction of the castle was completed in the XVI century.
