Square Paul-Langevin, Urban park in 5th arrondissement, Paris, France.

Square Paul-Langevin is a park with winding pathways and gardens featuring magnolias, ash trees, and sycamore maples. The roughly 4,300 square meter space offers varied areas for walking and resting.

The park was created in 1868 as Square Monge and contains architectural elements from the 1889 World's Fair Palace of Fine Arts. These historical components shape its appearance today.

The Villon statue here is a 1946 state commission to René Collamarini, a sculptor who frequented the square; the earlier bronze Villon by Jean-François Etcheto left for Champigny-sur-Marne in 1950. Two Renaissance-style niches from the old town hall, burned in May 1871, keep their place, though the statues of Jean Aubry and P. de Violes they held, decapitated during May 1968, were never reinstalled.

The square has three entrances, at the corner of rue des Écoles and rue Monge, and is open during set hours. Inside are a children's play area, drinking water points and public toilets. Maubert - Mutualité station on metro line 10 is the nearest stop.

The staircase beside the square is covered with ivy and Turkestan knotweed, not the viburnum often mentioned. The bronze François Villon by Jean-François Etcheto, now known as Le Troubadour in Champigny-sur-Marne's garden city, stood here before escaping the 1944 metal requisitions and being offered to that Val-de-Marne commune in 1950.
