The Pré des Lavandières is a park which was completed in three years by landscape gardener Erwan Tymen, and opened in 1989. It boasts perennial and self-sown plants, which occupy large spaces and create a welcome link to the garden’s more tended areas. Wetland trees and shrubs were chosen to adorn the park. Its location, close to the town centre but still in a natural setting on the banks of the Vilaine river, make it an ideal spot from which to admire the walled town, the château, the Rachapt quarter and the 19th century Bouin tannery.
