"broach spire" の定義と意味

What is a "broach spire"?

A broach spire is a tall, pointed structure that rises from the roof of a building, often seen on churches and cathedrals. This type of spire is characterized by its broad base, which gradually tapers as it ascends, typically featuring a square or octagonal shape at the bottom before reaching a pointed top. Broach spires often have a decorative design and are commonly adorned with various features, such as decorative knobs or small statues. They serve to enhance the verticality of the building, drawing the eye upward and contributing to the overall grandeur of the structure.
