Retronaut has wonderful photos of the Middle East taken by Félix Bonfils in the late nineteenth century.
Below, a fab panorama of Jerusalem. And there are photos of the church of the Holy Sepulchre, complete with ladder (which is still standing there today).
And I love this one of the road to Bethlehem from the Jaffa gate.
I often use older photos in my books because I think they give more of an impression of the ancient city – at least in scale and size. (Also they’re out of copyright which always helps!)
