Designated a World heritage Site by UNESCO in 1979 the Cathedral of Notre-Dame de Chartres was built from between 1145 and 1250. It's high nave is spanned by ogival pointed arches to form the vault, and the walls are supported by double flying buttresses. Chartres is the first building to have used buttresses as a structural element.
Chartres Cathedral is also unique in having retained almost all of its original 12th and 13th century stained glass.
