6. Predjama Castle, Slovenia
This European castle is special because it is built within a cave, which you don’t see every day. The castle’s placement is strategic, as they wanted it to be difficult to access and easy to get out of it because it has secret tunnels.
As with many other castles, it was reconstructed more than one time. The final form was done in 1579 and was built in the Renaissance style and is placed right next to where the original used to be.
The castle was later inherited by Count Michael von Cronberg and sold to another family that remained the owners until the end of World War II when it was confiscated and nationalized by the Communists and turned into a public museum.
There are so many fascinating stories behind these charming castles, what do you think?
