It's pretty sad in terms of losing a near-millennium old building that was very cool looking and took a very long time to make. Especially the fact all the original stained glass got fucked and that shit is lost so.
On why it can be considered funny is cus the French were one of the biggest offenders for colonization. They destroyed, burned, and stole any colony's monuments, artifacts, and pieces of cultural significance. So in sense a bit of karma
