Build diagonal braces on the outside of the cathedral

Diagonal braces are a great idea for tall skyscrapers that sway back and forth in the wind, but not for walls that fail under a heavy arch ceiling. The heavy dome is pushing the cathedral walls outward. You need something to push them back. Diagonal braces won't do this. Besides, they would conceal sections of the stained glass windows.

Do you really want to do this? There's another way to strengthen this cathedral without detracting from its beauty.
