Mabillon is a station on line 10 of the Paris Metro, located at the heart of the Rive Gauche and the 6th arrondissement. It was named after the nearby street, rue Mabillon, which in turn was named after Jean Mabillon, a Benedictine monk and scholar, considered the founder of palaeography and diplomatics, who died nearby.
Although the station is in close proximity to Saint-Germain-des-Prés on line 4, there is no free transfer between the two stations.
