Named after the avenue de la Liberté in Charenton-le-Pont, after the first word of the French motto.
Liberté, égalité, fraternité is the motto of the French Republic. In the 14th century the avenue was a path, the chemin de la Vierge, leading to the château de Conflans; widened in 1620 into an elm-lined avenue, it was renamed avenue de Conflans. We have not found out when it became the avenue de la Liberté.
