The Boulevard Saint-Germain (French pronunciation: ​[bulvaʁ sɛ̃ ʒɛʁmɛ̃]) is a major street in Paris on the Left Bank of the River Seine. It curves in a 3½ kilometre arc from the Pont de Sully in the east (the bridge at the edge of the Île Saint-Louis) to the Pont de la Concorde (the bridge to the Place de la Concorde) in the west and traverses the 5th, 6th and 7th arrondissements. At its midpoint, the Boulevard Saint-Germain is traversed by the north-south Boulevard Saint-Michel. The boulevard is most famous for crossing the Saint-Germain-des-Prés quarter from which it derives its name.
