Inside the town hall, this museum displays an interesting and well-presented exhibition on the town's history, and the building's original interiors are worth the entry price on their own. The Gothic vaulted cellars are the only remains of the first town hall. They were initially used for trade but later became a jail.
The first floor is home to three splendid rooms. The largest, the richly ornamented Renaissance Hall, is a real gem, with its original stucco work and paintings from 1555. The 2nd floor contains artefacts from the Prussian/German period, documents illustrating city life in the 1920s and '30s, and a collection of interesting memorabilia from the past two centuries.
In front of the building, near the main entrance, is the pręgierz (whipping post), once the site of public floggings – and of more serious penalties. The original miniature model executioner which accompanied the post, dating from 1535, is on display in the museum.
