I would have never noticed this, but there’s a wonderful Heritage Trail board nearby which explained what these marks are. They’re from a tank which drove down here, which is Nuns’ Bridges Road, during the Second World War. I can imagine the concern of the tank driver when he realised that his vehicle had damaged the bridge and perhaps threatened to knock the entire wall down into the stream below.
