Postojna and the village of Predjama are joined by 9 kilometres of winding road. Nowhere do you get such a strong sense of the Middle Ages as here below the sheer cliff that serves as a backdrop to the mighty Predjama Castle – a castle which even today is full of surprises. The sixteenth-century Renaissance castle conceals an even older nucleus – a true cave castle that reveals the image of past centuries and the castle's most famous owner, the robber baron Erazem.
