Pillbox

I went over to Ampthill this afternoon to check something out for the weekend.
On Sunday the four remaining chimneys at Stewartby brickworks are being demolished and I am planning to go over and watch. I wanted to see if a particular location would provide a good vantage point and it does - see extra.
Walking up the hill a little, I passed this WW2 pillbox, not easy to get a good shot through the hedgerow, but I wasn’t climbing over the fence!
