Following the destruction by fire of the choir of Canterbury Cathedral in 1174, a group of master builders was invited to propose plans for the reconstruction. The master-builder William of Sens, who had worked on Sens Cathedral, won the competition. Work began that same year, but in 1178 William was badly injured by fall from the scaffolding, and returned to France, where he died. His work was continued by William the Englishman who replaced his French namesake in 1178. The resulting structure of the choir of Canterbury Cathedral is considered the first work of "Early English Gothic". The cathedral churches of Worcester (1175–), Wells ("c".1180–), Lincoln (1192–), and Salisbury (1220–) are all, with Canterbury, major examples. "Tiercerons" – decorative vaulting ribs – seem first to be have been used in vaulting at Lincoln Cathedral, installed "c".1200. Instead of a triforium, "Early English" churches usually retained a gallery.
