Another remarkable artifact to see at the Museum of Crime is the blade of the first guillotine. This blade is from La Place de Greve — that is  where the executions would traditionally take place. Anyone who has seen the City Hall of Paris understands that there is not enough room in front of it to accommodate the kinds of crowds that would gather to witness the death of Louis XVI or Marie-Antoinette; yet the place had its advantages — you could rent yourself a balcony or a window to watch comfortably from above. According to Casanova, a little privacy could be a good thing, given that the sight of blood excites certain types of women.
