The Predjama Castle (Predjamski Grad) is a Renaissance castle located near Postojna, Slovenia. It is the best surviving example of a cave castle in the world and dates back to 1274.
The castle was visited as part of a tour of the Postojna Cave (Postojnska Jama), which is 9 kilometres away. My apologies for the poor camera work at times; the crowds were a challenge and I was also trying to take photographs at times.
