Joanne Woon just posted a comment on this site to alert me to an image of the Muski taken around 1900 that shows a street sign for the Hotel du Nil (click twice on the photo to enlarge). This hotel was rare among Cairo hotels in that it wasn’t in the modern city but hidden away in an alley deep in Islamic Cairo.
It comes from a set of wonderful photos mostly taken in the 1930s sourced from the Library of Congress, which was an invaluable source when it came to finding images to include in Grand Hotels of Cairo (less so for On the Nile). Point your browser over that way and you could spend hours lost in its image archive.
This could almost have been taken in taken in the last 20th century until you notice the guy at the far right in his Edwardian pith helmet.
What really dates the photo above is how clean it is. I’ve certainly never seen it like that. The images in this post and several more can also all be found here.
