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.
