This old hospital in the South of Germany was one of my spookiest explores, despite the fact the building is right in the centre of a very active town. It took a little bit of time to brave up and enter, not least because of the undergrowth on the way in. I even managed to tear my trousers with the climb! But it was worth it. Whilst a lot of this building is in a bad state (partially due to an arson attack in 2014), the gem that made it worthwhile is the blue operating theatre. Stunning.
