The Student Jail in Heidelberg, Germany, is an unusual attraction that serves as a testament to a unique aspect of the city's university history. Spanning a period from the 1770s until 1914, the Studentenkarzer was a detention center for students who committed minor offenses like disturbing the peace, dueling, and nocturnal drunkenness. Rather than being a somber place, the jail became a rite of passage for mischievous students, a place where they could serve their time while continuing their studies. They often left graffiti, poems, and paintings on the walls, which remain visible today. Located behind the Old University building, the Student Jail is part of the University Museum. It has two floors and several cells, through which visitors can walk to glimpse students' lives during this period. The tradition underscores the autonomous jurisdiction that the university once had over its students. The facility is now a popular tourist site, reflecting a quirky piece of Heidelberg University's history and offering insight into the student culture of the past.
