Stained Glass
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.
In 1834 the London Wine merchant James Powell (1774-1840) bought the small Whitefriars glassworks just off Fleet Street as a business for his sons. Originally unfamiliar with glass production the company experiemented with different techniques and were soon supply patent glass to other leading stained glass companies and designer as well as making stained glass windows of their own.
