 The pointed arch lends itself to a suggestion of height.This appearance is characteristically further enhanced by both the architectural features and the decoration of the building.On the exterior, the verticality is emphasised in a major way by the towers and spires and in a lesser way by strongly projecting vertical buttresses, by narrow half-columns called "attached shafts" which often pass through several storeys of the building, by long narrow windows, vertical mouldings around doors and figurative sculpture which emphasises the vertical and is often attenuated.
