This old town in Germany is the country’s best preserved medieval walled town. There is a wall surrounding it that was constructed in 1200’s. In the middle ages towns needed to protect themselves from raids and sieges, this wall worked very well for the people.
This guy dresses up as a night watchman and gives a walking tour in the evening. At least 100 people turned up for it! He must make a lot of money for one hour of work… Night watchmen were employed by the town until 1920 to watch over it for fires and raids while everyone slept.
