Try Poitiers. Richard the Lionheart built chateau, Eleanor of Aquitaine lived here etc., the battle of Poitiers pushed back the Saracen advance into Europe. Lots of history. It was heavily bombed at the end of the war (by us, to cut communications) but is still very interesting all around and is not well known. There is also Futuroscope for those interested. Lots of things to do, but I think I'd hire a car.
