As I was flicking through the Stoke Newington OS map from 1868 (it’s a gripping read) I noticed that, north of the avenue and embankment that was once the New River, was a stone. No other explanation. Just “stone”. Was it a milestone, like the one on the bend of the New River near St Mary’s church? Maybe this is the same stone and it was moved into an enclosed area for safe keeping. Or was the “stone” something else, something older still? Like a neolithic marker which, though long gone, still gives off a strange magnetic pull that attracts summertime frisbee throwers and the Turkish football team (it’s near the spot where they do their windsprints).
