With its 9,000 m² of windows, the Aube is the richest département in France for stained glass. Troyes, its medieval city with ten churches, is a perfect destination to discover this exceptional religious heritage. The Aube, its vineyard countryside, forests and hills, also offers other unmissable things to do and see, such as its Champagne trail and cellars, its large lakes great for sports activities, and its delightful timber-framed churches.
