In 1340 the castles at Ranton and Curçay-sur-Dive were re-built; that of Ranton by Guillaume de Bois Gourmont and that at Curçay by Huet Odart, both under instructions from Jean II; they were part of an elaborate network of fortresses that ensured that the area remained under French control. The castle at Ranton was only one of those rebuilt by Guillaume de Bois Gourmont: the largest was that at Bois Gourmont, near Veniers, just north of Loudun, of which only the ruined keep now remains.
