Some elements of Gothic style appeared very early in England. Durham Cathedral was the first cathedral to employ a rib vault, built between 1093 and 1104. The first cathedral built entirely in the new style was Sens Cathedral, begun between 1135 and 1140 and consecrated in 1160. Sens Cathedral features a Gothic choir, and six-part rib vaults over the nave and collateral aisles, alternating pillars and doubled columns to support the vaults, and buttresses to offset the outward thrust from the vaults. One of the builders who is believed to have worked on Sens Cathedral, 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.
