"Built between 1170 and 1547, the Cathédrale St-Gatien is a must-see when visiting Tours. Listed as a historic monument in 1862, it features an exquisitely detailed facade, a 16th-century organ, and the beautifully sculpted tomb of Charles VIII and Anne of Brittany’s children. The cathedral’s pièce de résistance, however, is its 8,600-foot-high choir area, which features 15 Gothic-style, stained glass windows, with explanations in English."
