Chartres is a commune and capital of the Eure-et-Loir department in France. It is located about 90 km southwest of Paris. Chartres is famous world-wide 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. Much of the old town, including the library associated with the School of Chartres, was destroyed by bombs in 1944.
