From 1823 to 1914, students convicted of misdeeds such as public inebriation, loud nocturnal singing, freeing the local pigs or duelling were sent to this student jail for at least 24 hours. Judging by the inventive wall graffiti, some found their stay highly amusing. Delinquents were let out to attend lectures or take exams. In certain circles, a stint in the Karzer was considered a rite of passage.
