Predjamski Grad (Predjama Castle) is perhaps the most famous cave castle in the world. The castle is located in a 123 m high limestone cliff, inside the entrance of a cave. This extraordinary and romantic location made it well known. The site was a location for movies multiple times, mostly for historic, fantasy, and fairy tale movies. Since some years there is an annual Medieval festival right in front of the castle, which offers a great background. The castle floor plan was used in the computer game Counter-Strike: Global Offensive.

The modern name is Slovenian, but until World War I this area belonged to the Austro-Hugarian, and the German name is Höhlenburg Lueg, or actually Burg Lueg. It was first mentioned in 1274 with the German name Luegg, when the Patriarch of Aquileia built the castle in Gothic style. It was later acquired and expanded by the noble family known as the Ritter von Adelsberg (Knights of Postojna). From then on they were called von Luegg after the castle. Between the World Wars the area was Italian, and the Italian name was Castel Lueghi.

The cave behind the castle is called Erazmova Jama (Erasmushöhle), after the knight Erasmus von Luegg, who lived in the castle according to legend. The huge cave system has four levels. The deepest level is water filled, the river flowing through is called Lovka. The Lokva sinks into the cave at the foot of the cliff face, right below the castle, and the river flows into the Mediterranean sea. The castle is built into the huge entrance of the middle level. An exit from the top level to the plateau was used as secret entrance in the Middle Ages, today it is filled with rocks.

The story goes, that the castle was besieged, but the people in the castle had the secret entrance, and so they had enough to eat. They laughed on the besieger and threw down fresh fruit, to discourage them. Although he was a brave and almost unbeatable knight, Erazem reportedly died while using a toilet after a betrayal by his servant.
