Once upon a time… there was a castle built inside a cliff. 🏰 Predjama Castle looks like something from a storybook, but its history is very real and full of secrets. Built into a 123-metre-high cliff, this medieval castle has stood here for more than 800 years and is closely connected to the legend of the knight Erazem of Predjama.

Postojna Cave is one of those places that sounds made up until you’re actually there.

You take a train deep underground, explore one of Europe’s largest cave systems on foot, and somehow end up finding a post office hidden inside a mountain.

Slovenia keeps surprising me.
