As a side note, it can be a permanent thing for some cathedrals. I'm thinking of Beauvais Cathedral: https://commons.wikimedia.org/wiki/Category:Interior_of_Cath%C3%A9drale_Saint-Pierre_de_Beauvais#/media/File:Beauvais_-_La_Cath%C3%A9drale_Saint-Pierre_de_Beauvais_-_North_Transept_-_North_Entrance_-_View_SSW_%26_Up_on_South_Transept,_Central_Crossing_(Wooden_Vaults)_%26_North_Transept.jpg https://commons.wikimedia.org/wiki/Category:Interior_of_Cath... This cathedral is the highest in France, but it had some design flaws, with part of the vault collapsing during the construction, and then, the huge spire collapsed during Ascension Day in 1573. It was never finished because of that. This cathedral is also quite interesting because of this unfinished state as it permits to compare the old roman cathedral vs the new gothic cathedral, showing the huge increase in scale between the twos: https://commons.wikimedia.org/wiki/Category:Cath%C3%A9drale_Saint-Pierre_de_Beauvais#/media/File:Beauvais_-_Rue_Saint-Pierre_-_ICE_Photocompilation_Viewing_from_North_to_East_on_L%27%C3%89glise_paroissiale_Notre-Dame-de-la-Basse-%C5%92uvre_de_Beauvais.jpg https://commons.wikimedia.org/wiki/Category:Cath%C3%A9drale_... https://en.wikipedia.org/wiki/Beauvais_Cathedral https://en.wikipedia.org/wiki/Beauvais_Cathedral
