Cathedral of St. Gatien (Cathédrale Saint Gatien de Tours), Tours

The Cathédrale St-Gatien, built between 1239 and 1484, reveals a mixture of architectural styles. The richly sculpted stonework of its majestic, soaring, two-tower facade betrays the Renaissance influence on local château-trained craftsmen. The stained glass dates from the 13th century (if you have binoculars, bring them). Sheltered inside is the handsome 16th-century tomb of Charles VIII and Anne de Bretagne''s two children; and the Cloître de La Psalette (cloister), on the south side of the cathedral.
