spire
Let an agent identify spire types and traditions, explain their construction and conservation, and support heritage and design questions.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent identify spire types and traditions, explain their construction and conservation, and support heritage and design questions.
A tall, tapering structure on top of a tower, roof or building, typically conical or pyramidal, found on churches, cathedrals, temples and civic buildings in forms such as the broach spire, fleche, ridge turret and, in Indian architecture, the shikhara and bhumija; spires mark landmarks, carry symbolic meaning and pose engineering and conservation challenges.
What it is for: Architecture, heritage and landmarks.
It can be identify spire types and styles; explain construction and materials; support conservation and repair; describe symbolic and regional traditions.
