The High Castle (Hohes Schloss) in Füssen is known for its walls decorated with a 15th-century Trompe l’oeil. Personally, I was impressed by a couple of ‘painted’ oriel windows which give the castle a surreal touch.
This is another example of a Trompe l’oeil located in the courtyard of the castle and displaying an oriel window. As there are a lot of such oriel windows you have the crazy feeling to be watched all the time.
