Point of interest – The Sienne
As you pass the Sey Mill, you’ll come across the Sienne: this coastal river, which flows into the Regnéville Harbour, is a gathering place for long-distance migratory birds. In autumn, Atlantic salmon leave the sea and swim upstream to spawn. It is at this time of year that the pale-bellied brant goose, arriving from the Nordic countries, takes up winter quarters on the salt marshes of Regnéville Harbour. In summer, sea lampreys and river lampreys (jawless fish with a sucker) in turn gather at the spawning grounds on the River Sienne. Finally, let us not forget the eel, which colonises the freshwater of the catchment area after a long journey from its breeding grounds in the Sargasso Sea.

The ruins of the Sey Mill
Take a stroll through this peaceful spot, which invites you to relax. This site, with its untamed charm, offers glimpses of the bell tower of the village of Quettreville-sur-Sienne through the hedgerows. The former mill can be made out thanks to the remaining ruins. Built before the Revolution of 1789 and demolished in 1957, it was of great importance to the region, with its two water wheels mounted on each gable. Today, a footbridge spans the River Sienne above the ruins, linking the villages of Trelly and Quettreville-sur-Sienne. The site has now been developed to welcome visitors and for fishing in the River Sienne.

Saint-Louet
Saint-Louet-sur-Sienne is a former commune in the area, near the circular meanders of the River Sienne. During the Revolution (1794–1795), it was incorporated into the commune of Trelly at the request of its inhabitants. Today, the remains of the old 9th-century church can still be seen in this hamlet, thanks to its bell tower which still stands in the heart of the bocage.

The Hermits’ Chapel
Built in 1903 by Madame de Bérenger, owner of Trelly Manor, this chapel is dedicated to the Black Madonna of Einsiedeln, housed in a monastery in German-speaking Switzerland. The chapel stands on private land but can be seen from the route.
