圣日耳曼大道
As well, parts of original streets have more or less been maintained in their original state, but incorporated into the Boulevard as short narrow sections separated from the main Boulevard by a traffic island. For example, there is the south side of the boulevard at the Place Henri Mondor, south of the Odeon Metro station, which is the former Rue des Cordeliers (later renamed Rue de l'Ecole de Médecine) and an extension of the current Rue de L'Ecole de Médecine, but is now considered as being the Boulevard Saint-Germain. Another example is the south side of the boulevard just east of the Rue des Ciseaux, which extends the current Rue Gozlin, formerly Rue Sainte-Marguerite. The north side of the Rue Gozlin and this short section extending it represent exactly how much further south the abbey extended before the creation of the Boulevard Saint-Germain.
