Watch FilmoFlix. Filmed around the famous circular medieval wash house built on an equally famous spring, the Fosse Dionne, in the medieval town of Tonnerre, Yonne. It is surrounded by wild flowers from abandoned terraces, plants in the St. Pierre gardens, cultivated by the disabled and the injured, which lead up to the church on the hill, flowers hanging down from pots, their reflections and others growing in or around the water's edges.
