Saint Peter's Cathedral (Cathédrale Saint-Pierre de Lisieux), Lisieux

This Norman Gothic cathedral was built between 1149 and 1230, making it one of the first Gothic churches in Normandy. The 110-meter-long structure features ribbed vaults, flying buttresses, and three distinctive towers including a 72-meter spire. Pierre Cauchon, the bishop who condemned Joan of Arc to death in 1431, later served here and built the Flamboyant Gothic Chapel of the Virgin where he lies in an unmarked grave.
