The building dates from 1552 and is built in Rhone Renaissance style. Three of the walls are decorated with fine paintings and allegories. On the right side of the building hangs a grimacing stone mask, a copy of the Klapperstein, weighing 12 to 13kg, that used to be hung around the necks of scandalmongers who were condemned to riding around town on a donkey, sitting back to front. The building also houses the History Museum.
