Spire

Spire

A spire is a tall, slender, pointed structure on top of a roof or tower, especially at the summit of church steeples. A spire may have a square, circular, or polygonal plan, with a roughly conical or pyramidal shape. Spires are typically built of stonework or brickwork, or else of timber structure with metal cladding, ceramic tiling, shingles, or slates on the exterior.Since towers supporting spires are usually square, square-plan spires emerge directly from the tower's walls, but octagonal spires either called for a pyramidal transition section called a broach at the spire's base, or else freed spaces around the tower's summit for decorative elements like pinnacles. The former solution is known as a broach spire. Small or short spires are known as spikes, spirelets, or flèches.This sense of the word spire is attested in English since the 1590s, spir having been used in Middle Low German since the 14th century, a form related to the Old English word spir, meaning a sprout, shoot, or stalk of grass.
