There is a lot going on at the top of this hill - four tall masts, two covered reservoirs, a trig point, some well-appointed houses, at least two pillboxes, a zig-zagging short underground tunnel, a Pilgrim Way walking route, and some farmland! The pillbox is on the right - there was once access to its base but this has since been blocked up. The hole at the bottom left of the picture is where some steps go down to a short tunnel that after seven 90° turns emerges by other steps right next to the mast on this same side. The slabs in the centre of the picture, which have what looks like a couple of fenceposts resting on them, indicate some of its course. I presume the tunnel was in some way linked to the pillbox.
