The Ghost Museum is a small family stop in central Plzen, built around fairy-tale figures, legends, and spooky local atmosphere rather than serious history. It sits close to the main square, so it is easy to fold into a short old-town wander.
This is best for children or for travellers who enjoy odd little museums. Adults looking for depth should choose the brewery, the underground, or the West Bohemian Museum first, but the Ghost Museum can be a fun rainy-hour diversion.
