Just uploaded a bunch of Charles Marville’s photographs of 1860s Paris to Photobucket—go have a look! Marville was specifically tasked with photographing all the streets about to be destroyed in Haussmann’s demolitions, so almost all of the places in these photographs no longer exist. Also, most of them are old as balls.
This photo is of the Rue des Trois-Canettes, which was part of the rabbit warren of medieval streets on the Île de la Cité that Haussmann particularly wanted to clear out.
I can seriously picture Eponine walking down this street singing “On My Own”
