18th century Cassini map of France, detail of the surroundings south of Cosne, in the north-west of the present Nièvre departement, in Burgundy. The town of Cosne is centered on the upper edge of the picture, standing on the right bank of the Loire river that crosses the picture in roughly south-west/-north-east direction. The "road (from Paris) to Lyon through the Bourbonnais" also crosses the picture, coming due south from Cosne. The river reaching Cosne and the Loire from the south-east is the Nohain. After Cosne, the main town is Bannay, showing here on the left bank of the Loire (therefore in the present Cher département). Many small villages and hamlets are indicated on the map. <a href="https://fr.wikipedia.org/wiki/ch%C3%A2teau_de_Villechaud" class="extiw" title="fr:château de Villechaud">Villechaud <i>(fr)</i></a> is 4.5 km south of Cosne, about 1 mi west of the road to Lyon and 1/2 mi east of the Loire river. 1/3 of a mile south-west of it is Villefroide, another hamlet.
