Cimetière de Montmartre, in Paris’ 18th arrondissement, did not have the most glamorous or auspicious of beginnings. It was originally a gypsum quarry, situated outside of the city walls, and after the quarry was abandoned, a section of it was used as a mass grave during the turbulent years of the 1790s. Yet this rather grim location was over time transformed, and it is now a peaceful haven where thousands of Parisians lie at rest beneath beautiful memorials.
