A pillbox dating to World War Two is visible on 1952 RAF aerial photographs (S1). It measures 5m across and the walls are 1m thick. It appears to be slightly dug into the side of the slope and has lost its roof.

No trace of this was found, only two overgrown earthwork trenches or gullies with a wooden lintel to a buried chamber. The structure may have been buried in coastal defensive works, but might have been missed in the long grass.

Quite remarkably, (S2) shows a rectangle on this spot – apparently a small building with an attached courtyard like an animal stall. The pillbox may have been disguised inside this.
