All at once imposing and delicate with its filigree stonework, Troyes' cathedral is a stellar example of champenois Gothic architecture. The flamboyant west façade dates from the mid-1500s, while the 114m-long interior is illuminated by a spectacular series of 180 stained-glass windows (13th to 17th centuries) that shine like jewels when it’s sunny. Also notable is fantastical baroque organ (1730s) sporting musical putti (cherubs), and a tiny treasury (open July and August only) with enamels from the Meuse Valley.

Back in 1429, Joan of Arc and Charles VII stopped off here on their way to his coronation in Reims.
