Let's have a proper castle thread!
Preferably post castles from your country that you find interesting. And maybe write some additional info text about them.

I'll start with the Burg Hohenzollern - the ancestral castle of the Hohenzollern dynasty from which the German Emperors of the 19th and early 20th centuries hailed. Of course the contemporary appearance obviously isn't medieval - the castle got destroyed in the middle of the 18th century and was rebuilt as a palace from 1850 to 1867.
