Chartres (French pronunciation: [ʃaʁtʁ]) is a commune and capital of the Eure-et-Loir department in France. It is located 96 km (60 mi) southwest of Paris. This city is well known for its cathedral.
Chartres was in Gaul one of the principal towns 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 countship 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.
