Neuschwanstein Castle is rumoured to have been the inspiration for Disney’s castle. There are plenty of other candidates but I am sure it had some influence.
We drove there a few years ago from Munich to the site in south-west Bavaria. A fierce snowstorm accompanied us for much of the journey, and returning after dark was a pretty hairy experience.
It was worth it though as we viewed the castle with a snowy backdrop and with hardly any other visitors. We even had a fun snowball fight!
