Friends of mine lived for a while in Rennes in one of the only buildings to survive a fire in the 18th century. It was from 15-something and had nary a right angle to it. A bit scary to go up the stairs, but quite cool.

Lyon's Musée de l'Imprimerie et de la Communication graphique is also 15th century and very oddly angled. https://www.imprimerie.lyon.fr/en/edito/presentation_musee https://thisislyon.fr/things-to-do/museums/museum-of-printin... Also in Lyon, the church of Saint Paul was built in 549 and rebuilt in the 11th and 12th centuries.
