Spire

Spire of Salisbury Cathedral (completed 1320) (404 feet (123 metres), with tower and spire)

A spire is a tall, slender, pointed structure on top of a roof of a building or tower, especially at the summit of church steeples.^[1] A spire may have a square, circular, or polygonal plan, with a roughly conical or pyramidal shape.^[1] Spires are typically made of stonework or brickwork, or else of timber structures with metal cladding, ceramic tiling, roof shingles, or slates on the exterior.^[1]

Since towers supporting spires are usually square, square-plan spires emerge directly from the tower's walls, but octagonal spires are either built above a pyramidal transition section called a broach at the spire's base, or else free spaces around the tower's summit for decorative elements like pinnacles.^[1] The former solution is known as a broach spire.^[1] Small or short spires are known as spikes, spirelets, or flèches.^[1]^[2]
