A few kilometres from the entrance to Postojna cave stands one of the most picturesque buildings in the whole of Slovenia. Predjama Castle hangs dramatically in the middle of a 123 metre cliff a four storey structure almost arrogant in its simplicity, but unconquered and uncompromising. Although the current building dates from the end of the 16th century, a castle has stood on this site since the year 1201. It does not take much imagination to see how Predjama castle would be the ideal stronghold for a wilful, rebellious knight and indeed just such a romantic legend survives: the story of the robber baron Erazem, who is today commemorated by the recently opened Erazem's Passage. The castle is well worth a visit. And not just the castle; visiting the underworld below the castle is an adventure in itself, whether you are a caver, a tourist or simply curious.
