spire. Tall structure, circular, polygonal, or square on plan, rising from a roof, tower, etc., terminating in a slender point, especially the tapering part of a church-steeple. Often of stone, and occasionally of brick, it was also built as a timber-framed structure clad with copper, lead, shingles, slates, tiles, or thin stone slabs. If square, a spire rises directly from the tower, but octagonal spires required the top of the tower not covered to be occupied by pinnacles or by an arrangement (broach) forming a transition between the square and octagon resembling part of a pyramid and sloping towards the spire (broach-spire (a) ). Other types of spire include:crown spire: spire carried on buttress-like elements, i.e. with the structure fully exposed, resembling the arched forms at the top of a crown (b);Hertfordshire spike: small needle-spire rising from a tower behind a parapet;needle-spire: very tall slender spire rising from a tower behind a parapet, like a Hertfordshire spike but much bigger, taller, and finer (c);spike: short spire, flèche, or spirelet;splay-foot: spire with a base opening out at a flatter pitch and forming eaves over the tower.
