The Château de Leynes is an old fortified castle and priory in the commune of Leynes in the Saône-et-Loire département of France. The estate of Leynes was granted by Charles the Bald in a charter dated 19 March 875 to Tournus Abbey, a gift confirmed by the Pope in 1119. The castle however, also the property of the abbey of Tournus, is not recorded until a document of 1423 mentions it for the first time in connection with the civil war between the Armagnacs and the Burgundians, when the Armagnacs occupied it. The castle today has been renovated and is used as a guest house and gîte.
