Boulevard Saint-Germain
Fontaine de l'Abbaye de Saint-Germain-des-Prés, or Fontaine Childebert. Originally at the corner of rue Childebert and rue Sainte-Marguerite, (1715–1717), by architects Victor-Thierry Dailly and Jean Beausire. Dismantled to make way for Boulevard Saint-Germain and moved to square Langevin, against the wall of the former Ecole Polytechnique.
