Richelieu – Drouot has a black marble war memorial dedicated to metropolitan railway employees "mort pour la France", sculpted by Carlo Sarrabezolles in 1931. The central pillar is a caryatid, who supports the surrounding stone with her raised arms. The caryatid divides the names of subway employees killed during World War I into two half-circles. The monument's base contains the names of the Great War battlefields, and the word "Release" was added to the bottom right after World War II to commemorate employee participation in the French Resistance.
