Château de Chenonceau
The cathedral of Tours, dedicated to Saint Gatien, its canonized first bishop, was begun about 1170 to replace the cathedral that was burnt out in 1166, during the dispute between Louis VII of France and Henry II of England. The lowermost stages of the western towers ("illustration, above left") belong to the 12th century, but the rest of the west end is in the profusely detailed Flamboyant Gothic of the 15th century, completed just as the Renaissance was affecting the patrons who planned the châteaux of Touraine. These towers were being constructed at the same time as, for example, the Château de Chenonceau.
