First World War pillbox and associated Second World War anti-tank cubes, Sea View, Saltfleetby

Pillbox, built 1917, associated with a row of Second World War anti-tank cubes, built around 1940.

MATERIALS: in-situ poured reinforced concrete.

PLAN: trapezoidal plan.

EXTERIOR: situated below the crest of the eastern slope of the sea bank at Sea Farm, Saltfleetby, the NW and SE elevations each have a single, low set, wide-splayed machine gun embrasure that is partially obscured by slumping ground, and only the top of an off-set set doorway in the rear elevation is visible. The roof has irregular applied lumps of concrete to disrupt the outline of the structure, a blocked circular vent, and two threaded holdfast bolts. The exterior of the structure has a relatively smooth surface, having been cast with timber shuttering.

INTERIOR: now largely filled with sand. The walls have smooth whitewashed concrete surfaces, with horizontal plank shuttering witness marks and a timber batten on the NE wall.

SUBSIDIARY FEATURE Second World War anti-tank cubes: a single row of '5 foot' (1.5m) concrete anti-tank cubes, situated approximately 50m to SE to obstruct the exit off the foreshore. The cubes are set corner-on (diamond set) towards the line of expected attack. They are not mapped due to survey difficulties.
