This area has been saved from urbanisation and is a green space of around 100 hectares. To the south, there are plans to create a flower canal and 44 plant pots. Today, 34 hectares are secure and they open up to the Espace des Blondeaux in the north. In summer, pony rides are offered at 1 euro each. In festival season, "Le Lilabyrinthe" offers recreational activities based on horicultural activities. There are collections of lilacs, roses and fruit trees. Current size: 34 hectares.
