Museum of the History of Medicine
12 Rue de l'École de Médecine
Located in the university, this terrifying museum houses one of the oldest collections of medical instruments in Europe. The instruments, some of which date back several centuries, look downright crude today -- but most of these actually worked, albeit painfully. For example, you can check out a scalpel belonging to Dr. Felix, the man who operated on Louis XIV’s anal fistula in 1686. The king went on to die at age 76, so apparently, the good doctor did something right.
