Chartres Cathedral
First built in 1194, the breathtaking Chartres Cathedral is a UNESCO World Heritage site and an icon of Gothic architecture. Its mismatched spires give it a striking look, and the interiors are pretty impressive, too—the sculptures of saints and the "monumental screen" that surrounds the choir are intricate, and visitors come from around the world to see the cathedral’s relic, the dress reportedly worn by Mary when she gave birth to Jesus.
