Overview

Half castle, half cave

Predjama means 'in front of the cave', and the name is exact. The castle's rear walls are the rock itself; rooms end in bare limestone, and rainwater is collected from drips in the ceiling. A fortress has stood here since at least the 13th century. The building you see took its present shape around 1570 under the Cobenzl family, whose coat of arms sits above the gate.

Its position made it close to impregnable, which is the point of its best-known story.

The legend

Erazem and the siege

Erazem of Predjama was a 15th-century knight who fell out with the Habsburg emperor Frederick III and took to raiding from his cave castle. In 1484 an imperial army besieged him for more than a year without success.

According to legend he taunted the besiegers with fresh cherries and roast meat, brought in through a hidden passage in the cave behind the castle. He is said to have been killed by a cannonball after a servant signalled the moment he visited the castle's most exposed room: the privy.

Fourteen kilometres of cave

The cave under the castle is the second-longest in Slovenia fitted for visitors, on four levels linked by shafts. The stream Lokva sinks beneath the cliff and resurfaces near Vipava.

There is no electric light. Tours go in with hand lamps and only in the warmer months, because the cave shelters a colony of bats that must not be disturbed while they hibernate.

Before you go

Getting there

Predjama is 9 km north-west of Postojna along a country road. In summer a shuttle bus usually links the castle with Postojna Cave for holders of a combined ticket; otherwise you need a car, bicycle or taxi.

On the visit

The castle is toured with an audio guide and takes about an hour. Expect narrow stairs. The cave beneath is a separate guided tour, run in season only, and adventure tours of the deeper levels can be booked in advance.

Good to know

The classic photograph is taken from the meadow below, best in morning light. A medieval tournament named after Erazem is traditionally held beside the castle in summer.
