The Arboretum de l'École du Breuil, in the park's southeast corner, is a municipal arboretum established at this location in 1936. It was created in 1867 by Baron Haussmann as the city's school of horticulture and arboriculture. Today the arboretum contains about 2000 trees, as well as notable collections of shrubs, four hundred varieties of heritage apple and pear trees, and three hundred varieties of lilac.
