Étang de la Nauvinais

The Étang de la Nauvinais, a natural jewel in Brittany, seduces with its tranquility and biodiversity. Calm waters, lush green shores and migratory birds create an enchanting haven of peace.

Old Mill Ruins

Highlight • Monument

It stands out against the horizon quite far away.
