The park of the castle of Bourron, enclosed by walls, deploys its 40 hectares of lawn and wood, in the extension of the forest of Fontainebleau. It reveals some surprises: hidden behind the small house, the romantic spring of Neolithic times called Source Saint-Sévère that gives birth to the canal; the statue of Ceres that closes the northern parterre, that of Saint Joseph by Fernand Py under the futerias and the house of Artagnan. But the main axis of this French-style park remains the great perspective, driven to the south by the canal and the lime paths that give the Château de Bourron all its greatness. The site was added to the additional inventory in 1926 and has been listed as a historical monument since 1971.
