Square des Récollets, located at 86 Quai de Valmy in Paris’s 10th arrondissement, is a delightful green space open 24/7, dating from 1891. Nestled alongside the Canal Saint‑Martin, the park stands in a historically rich setting shaped by former river-port industries, Napoleon’s “granary of abundance,” and industrial activity that has all but vanished.

Shaded by twin rows of horse-chestnut trees, the square offers a peaceful ambiance and a focus on leisure: a playground, ping-pong tables, a foosball table, and drinking fountains make it a lively spot for families and passers-by. As an Eco‑garden, it also reflects ecological values.

This place is popular among families with kids, students looking for a calm corner, locals in need of a break, and joggers or cyclists using its tree-lined paths. In summertime, impromptu picnics animate the grass; in winter, the square takes on a hush, contemplative character. One can almost hear "Atmosphere, atmosphere…" on the footbridge, an echo of the nearby Hôtel du Nord film.

Just steps away, the 17th-century Couvent des Récollets stands at 150 rue du Faubourg‑Saint‑Martin. Transformed into the Villemin military hospital, later an architecture school, and now home to the Maison de l’Architecture and the International Welcome & Exchange Centre, it also features Café A and a hidden garden accessible through its historic arcade courtyard. Café A, celebrated for its artistic decor and secret garden terrace, serves drinks and brunches (Tuesday to Sunday).

Practical info: the park is reachable via Jacques Bonsergent metro (line 5), Gare de l’Est station, or buses. Entry is free and open, with no need to book. While there are no restrooms, this spot is perfect for families, wheelchair users, stroller rides, and cyclists.
