...Part of the GHQ Blue line of defences constructed during WWII▸ . Going up and down Burghfield Road you easily miss, probably more concerned about not meeting a tipper, skip, or concrete lorry.
Interesting, Sid. I wasn't aware of this particular part of the defence. A couple of years ago I wrote an article for the West Berkshire Countryside Society's quarterly newsletter about visible military features on sites where the Society does environmental work. I included Bucklebury and Snelsmore commons and Sulham Valley, through which an anti-tank ditch was dug during WWII from Theale to the Thames in Pangbourne. Once the invasion threat had gone, it was filled in. Many pill boxes remain, and there are a few concrete "dragons' teeth" in the hedge alongside Sulham Lane, near Oaklands Farm. Not a lane I care to walk along, though I see the occasional runner (though no longer the pony & trap that I came up behind several times some years ago).
And, as mentioned several years ago in the Coffee Shop, there's the pill box on the railway embankment close to the Roebuck Inn (as was) in Oxford Road, Tilehurst.
