The eastern portal of Devonshire Tunnel, which formerly took the Somerset & Dorset Railway beneath the southern edge of Bath. After many years blocked up - the Western portal was completely buried when the approach cutting was filled in in 1973 - the tunnel has recently been reopened as part of the Two Tunnels Greenway, a footpath and cycleway to Midford along the route of the old S&D. It's interesting to note that the telegraph pole on the right has survived all the changes ... I have a picture in Mac Hawkins' excellent "Somerset & Dorset: Then and Now" book which shows this very telegraph pole in 1958, when the railway was still open.
