 One of the builders who is believed to have worked there, William of Sens, later travelled to England and became the architect who, between 1175 and 1180, reconstructed the choir of Canterbury Cathedral in the new Gothic style.Sens Cathedral was influential in its strongly vertical appearance and in its three-part elevation, typical of subsequent Gothic buildings, with a clerestory at the top supported by a triforium, (not a gallery as in earlier buildings, except in England) all carried on high arcades of pointed arches.In the following decades flying buttresses began to be used, allowing the construction of lighter, higher walls.
