Muenster's City Museum is a useful stop before or after exploring the Prinzipalmarkt and cathedral quarter. Its exhibits explain the city's bishops, merchants, Anabaptist episode, wartime destruction, and careful rebuilding, all of which are easy to flatten into pretty-old-town impressions.
The museum is central and manageable, making it a practical context stop rather than a long commitment. It helps Muenster feel less like a postcard and more like a city with sharp religious, political, and architectural turns.
