Pinacle (architecture)

A pinnacle is an architectural element originally forming the cap or crown of a buttress or small turret, but afterwards used on parapets at the corners of towers and in many other situations. The pinnacle looks like a small spire. It was mainly used in Gothic architecture. The pinnacle had two purposes: Ornamental – adding to the loftiness and verticity of the structure. They sometimes ended with statues, such as in Milan Cathedral. Structural – the pinnacles were very heavy and often rectified with lead, in order to enable the flying buttresses to contain the stress of the structure vaults and roof. This was done by adding compressive stress (a result of the pinnacle weight) to the thrust vector and thus shifting it downwards rather than sideways. The accounts of Jesus' temptations in Matthew's and Luke's gospels both suggest that the Second Temple in Jerusalem had one or more pinnacles (το πτερυγιον του ιερου): Then he (Satan) brought Him to Jerusalem, set Him on the pinnacle of the temple, and said to Him, “If You are the Son of God, throw Yourself down from here. Some have stated that there were no pinnacles in the Romanesque style, but conical caps to circular buttresses, with finial terminations, are not uncommon in France at very early periods. Eugène Viollet-le-Duc gives examples from Saint-Germer-de-Fly Abbey and the Basilica of Saint-Remi, and there is one of similar form at the west front of Rochester Cathedral. In the 12th-century Romanesque two examples have been cited, one from Bredon in Worcestershire, and the other from Cleeve in Gloucestershire. In these the buttresses run up, forming a sort of square turret, and crowned with a pyramidal cap, very much like those of the next period, the Early English. In this and the following styles, mainly in Gothic architecture, the pinnacle seems generally to have had its appropriate uses.
