The Kaak was the pillory in the Hanseatic city of Lübeck. Since the 13th century, ...

... buildings on the Lübeck market in front of the city hall were called Kaak. The pillory also served the cities as an external sign of jurisdiction. The punishment consisted mostly of the public disgrace the condemned person had to endure which made life in the community very difficult. The punished person was exposed to the insults and violence of passers-by, which was not without danger. Throwing objects at the condemned and beating were common. In Lübeck, however, it was prohibited to throw solid objects at the person in the pillory.
