Architectural FAQs

What is the Cathedral made of?

The principal building material of the Cathedral is Indiana limestone, chosen because it is superior for both construction and carving.

How is the Cathedral structured?

The Cathedral is a solid masonry structure. The limestone blocks are laid one on top of the other, with mortar between them. The flying buttresses are also solid stone, and they help hold up the walls by bracing them. The roof is held up by a steel beam structure, but does not help hold up the rest of the Cathedral. If you removed the roof and booms, the Cathedral would stay standing.
