🌀 Le Moulin de Beauvais – Missillac (44) 📍 Located in the hamlet of Beauvais, this windmill is part of the rich rural heritage of the commune of Missillac, in Loire-Atlantique. Long forgotten in inventories, it still stands, maintained, and converted into a private residence. Although it is no longer in operation or open to the public, it remains a fine example of the conversion of an old mill, perfectly integrated into the local wooded landscape.
