St. Andrew's Cathedral (Bordeaux Cathedral), Bordeaux

Consecrated by Pope Urbain II in 1096, the Cathedrale St-Andre was built in the shape of a Latin cross with a unique nave that is over 124 meters (406 feet) long. One of the first Roman buildings in France, nothing remains today from the original construction except one of the nave's interior walls. The royal door dates back to the first half of the 13th Century, while the apse and transept are from the 14th and 15th Centuries. The marriage of Eleanor of Aquitaine with Louis VII, future king of France, was held in this cathedral in 1137. The organ is particularly noteworthy, and concerts are held regularly. The cathedral holds the title of Historic Monument in France, and is also inscribed as a World Heritage site by UNESCO since December 2, 1998.
