Between 1778 and 1914, university officials used this as a lock-up for students, mostly incarcerated for minor offenses. They could be held for up to 14 days and were left to subsist on bread and water for the first 3 days; thereafter, they were allowed to attend lectures, receive guests, and have food brought in from the outside. There's bravado, even poetic flair, to be deciphered from two centuries of graffiti that cover the walls and ceilings of the narrow cells.
