Silly-Gallieni : the Seine as a guiding thread.
The Silly-Gallieni neighbourhood occupies the western part of Boulogne-Billancourt. To the north, its limits are marked by Route de la Reine while to the west, the Seine forms a natural barrier bordered by Quai Alfonse Le Gallo. To the south, the district is separated from Billancourt-Rives de Seine by Avenue du Général Leclerc. Two bridges cross the Seine and connect the Silly-Gallieni district to the left bank of the river: Pont de Saint Cloud and Pont de Sèvres. To the east, the streets of Billancourt and Paul Bert as well as Avenue André Morizet mark the limits of the neighbourhood.
