Predjama Castle

Heading off to Slovenia, but on the way stopped at this amazing castle built into the cliffs.

You can google it for historical stuff, but did like the anecdote about the 15th-century robber-baron Erazem Lueger who was besieged and, instead of starving, taunted his attackers by sending them gifts of fresh cherries, using secret tunnels to smuggle supplies. The tunnels are still there.
