Description
Postojna Cave is one of the largest karst monuments and Slovenia's most visited tourist attraction. It features a vast network of tunnels, galleries, and halls with diverse karst formations and easy visitor access.
The cave is unique for its underground electric train and for giving visitors a close look at the proteus, an endemic aquatic salamander.
Nearby, Predjama Castle is situated in the village of Predjama, built into a 123-meter-high cliff. It is Europe’s only preserved cave castle and offers insight into medieval building techniques and strategies for protection.
The castle is famous for its 15th-century siege and its owner, the robber baron Erazem of Predjama, who resisted capture with secret cave passages. The Lokva River flows below the castle, adding to its distinctive setting.
