I don’t really have any strong opinions on architecture, but I’ll still get mad in this instance taking it as a proxy for the French state’s efforts to wipe out regional culture throughout its history. You have tons of regional languages, with their own rich cultures and histories, and France has systematically done its best to beat them out of existence. Bréton, Gascon, Picard, Occitane and Corsican, amongst many others, are all considered to be either definitely or severely endangered, according to their wikipedia articles. Even those whose wiki page doesn’t mention this, like Alsatian, still generally mention the speakers tending to be predominantly older adults, with fewer and fewer young people learning the language. I’ve seen stuff about there being positive results with revitalization efforts and bilingual schooling for some of them, but it gets me bummed out and angry to think it might be too little, too late, and all in the name of some misguided nation building policies.
