Chartres is famous worldwide for its cathedral. Mostly constructed between 1193 and 1250, this Gothic cathedral is in an exceptional state of preservation. The majority of the original stained glass windows survive intact, while the architecture has seen only minor changes since the early 13th century. Part of the old town, including most of the library associated with the School of Chartres, was destroyed by Allied bombs in 1944.
Chartres was one of the principal towns in Gaul of the Carnutes, a Celtic tribe. In the Gallo-Roman period, it was called Autricum, name derived from the river Autura (Eure), and afterwards civitas Carnutum, "city of the Carnutes", from which Chartres got its name. The city was burned by the Normans in 858, and unsuccessfully besieged by them in 911.
During the Middle Ages, it was the most important town of the Beauce. It gave its name to a county which was held by the counts of Blois, and the counts of Champagne, and afterwards by the House of Châtillon, a member of which sold it to the Crown in 1286.
In 1417, during the Hundred Years' War, Chartres fell into the hands of the English, from whom it was recovered in 1432. In 1528, it was raised to the rank of a duchy by Francis I.
In 1568, during the Wars of Religion, Chartres was unsuccessfully besieged by the Huguenot leader, the Prince of Condé. It was finally taken by the royal troops of Henry IV on 19 April 1591. On Sunday, 27 February 1594, the cathedral of Chartres was the site of the coronation of Henry IV after he converted to the Catholic faith, the only king of France whose coronation ceremony was not performed in Reims.
In 1674, Louis XIV raised Chartres from a duchy to a duchy peerage in favor of his nephew, Duke Philippe II of Orléans.
