Karen, we enjoyed an interesting stroll around Montmartre Cemetery (Cimetière de Montmartre) very much.

A macabre bit of cemetery trivia is the tomb of Charles-Henri Sanson, who was the royal executioner during the reign of King Louis XVI, and High Executioner of the First French Republic. He was 4th in a line of family executioners, was first to use the guillotine, and performed nearly 3,000 executions, including the beheading of the king himself. His son, Henri, next in line of hereditary unpleasantness, was the executioner of Queen Marie-Antoinette and is also buried in Montemartre.

The site of a former quarry, it also served as a mass grave during the Revolution.
Obviously this would be a daytime activity. :O)
