Church of Saint Paul - Saint Louis
 
Located in the Marais neighborhood, this Baroque church serves as the setting for Cosette and Marius’s nuptials in Les Mis. After the wedding, Hugo writes, “People halted in the Rue Saint-Antoine, in front of Saint-Paul, to gaze through the windows of the carriage at the orange-flowers quivering on Cosette’s head.” The Jesuits constructed Saint Paul-Saint Louis from 1627 to 1641, and the church’s 180-foot dome, intricate carvings and shadowy corners appear much as they did 200 years ago. Hugo was a parishioner of the church and donated the shell-shaped holy water fonts on either side of the entrance. Like Cosette, Hugo’s daughter Léopoldine was married in Saint-Paul in 1843.
