 Durham Cathedral was the first cathedral to employ the rib vault, between 1093 and 1104.After working on the early Gothic cathedral at Sens, the French master-builder William of Sens travelled to Canterbury to begin in 1175 a new Gothic choir for the archiepiscopal cathedral there.Before the work was finished, he was badly injured by a fall from the scaffolding at Canterbury, and had to return to France, where he died.
