I have seen and passed this castle for maybe more than fifty times. I was already there for around five times or more. This is the remains of the Wolfstein Castle in Neumarkt Upper, Palatinate in Bavaria, Germany. The castle was dais to be built around 1120. Sometimes there are plays and events in the castle initiated by a so-called group Wolfsteinfreunde.
Here is an image I took during my visit with a friend last month.
