On top of the building's South door is displayed a coat of arms carved in high relief and depicting St. Jacques le Majeur dressed as a pilgrim, between four smaller escutcheons.
Located in the extension of the Rue des Champs, next to the railroad tracks, the chapel is closed to the public and can only be seen from the outside.
