The fifteenth-century Château de la Roche-Jagu is on wooded slope above the River Trieux, with great views of the estuary. It has a re-created medieval garden with compartments of herbs bounded by box and an ancient oak tree (seventeenth century). The Ministry of Culture has categorized it as a 'Jardin remarquable' (Remarkable Garden) - along with 200 other gardens in France. The old castle with strongly fortified bastions was a fine place to live and also an observation point with views of maritime traffic on the river 'like an eagle looking for its prey'. The basins by the river are being transformed into a water garden.
