4. Chartres: Cathedrale de Chartres
The beautiful soaring spires, the porches which are elaborately adorned with detailed sculpture works, and the stained-glass windows from the 12th and 13th centuries, conjure up the realization that the Cathedrale de Chatres symbolizes the front runner of the echelon in French Gothic art.
Although in 1134 much of the town of Chartres was destroyed by fire, the cathedral miraculously survived and became a major pilgrimage destination as well as a UNESCO World Heritage Site in 1979. It truly is a masterpiece of French architecture.
