Kropotkin used to live in Brighton, and it turns out his name has been given to a local bus, which I now HAVE to add to my anarchist pilgrimage.
The bus company also tells me "He lived for many years at Chesham Street in Kemp Town and wrote some of his books there. Later he moved to Rottingdean." So maybe I can even find the houses?
Google street view shows us Kropotkin's old street.
