Louis Pasteur died on September 28, 1895 in Marnes-la-Coquette and was laid to rest in a Neo Byzantine style funeral chapel, the Crypt, at the heart of the Institut Pasteur.
Louis Pasteur had a state funeral, but his wife, Marie Pasteur, refused to allow Louis Pasteur to be interred in the Panthéon.
A crypt was therefore built, the work of architect Charles-Louis Girault, mosaic artist Auguste Guilbert-Martin, and painter Luc-Olivier Merson.
Through its magnificent multicolored mosaics, the chapel offers an overview of Louis Pasteur's discoveries.
Marie Pasteur was interred there in 1910.
