Second World War pillbox at Stone Cross

This is a Second World War concrete pillbox built around 1941-1942. It is made of reinforced concrete and has a rectangular plan with access and a blast wall at the rear. The main embrasures face east towards Pevensey Bay.

The pillbox is situated on raised ground at the northwestern corner of a field. It features cast buff concrete walls and a chamfered concrete roof. The eastern side has two wide embrasures with stepped concrete surrounds, while the southern and northern sides each have one of the same type of embrasure. The western side includes a narrower embrasure in the southern corner and a central projecting concrete entrance with a blast wall. Access from the north is over sloping soil that may hide steps, and there is a square aperture in the concrete to the south. Horizontal build lines across the pillbox indicate the layers of wood shuttered concrete used in its construction.

Inside, the pillbox consists of a single room with smoothed and painted concrete walls that thicken towards the floor. Each embrasure has a rebate for a gun mounting, and there is one largely complete example of a Turnbull gun mount, along with the remnants of three others.
