Fort St-André

King Philip the Fair (aka Philippe le Bel) wasn’t messing around when he built defensive 14th-century Fort St-André on the then border between France and the Holy Roman Empire: the walls are 2m thick! Today you can walk a small section of the ramparts and admire 360-degree views from the Tour des Masques (Wizards' Tower) and Tours Jumelles (Twin Towers). You can also tour the Abbaye et Jardins de l’Abbaye.
