The oldest photographic archive of France, started in 1851, is hosted in a fort built after the 1870 war to protect Paris. This photographic archive was built to picture the monuments of France to protect them. 27 pictures of the site (including plans) to see here: https://www.pop.culture.gouv.fr/search/mosaic?base=%5B%22Photographies%20%28M%C3%A9moire%29%22%5D&image=%5B%22oui%22%5D https://www.pop.culture.gouv.fr/search/mosaic?base=%5B%22Pho... Those pictures are themselves stored on that site. One can visit the site when it opens for the Journées Européennes du Patrimoine when such places with historical values are open to the public. Well, probably not this year :( Some of the photographs of this database are available online: https://www.pop.culture.gouv.fr/search/mosaic?base=%5B%22Photographies%20%28M%C3%A9moire%29%22%5D&image=%5B%22oui%22%5D https://www.pop.culture.gouv.fr/search/mosaic?base=%5B%22Pho...
