Did you know much of Notre Dame’s exterior used to be painted in vivid colors?
And the famous flying buttresses (which I don’t have a photo of) were installed because the original walls in the back were starting to fall outward. And then buttresses became all the rage. We call that architecture by accident.
Kind of like Queen Victoria’s receding hairline. (You know, because she had female pattern baldness, but because she was the queen, freaky high foreheads became fashionable.)
