World War II auxiliary hide or underground observational post.

Reasons for Designation

From the summer of 1940 England's defences were strengthened against the threat of German invasion. A large number of diverse defensive structures were built across the whole country, from road and rail blocks to underground ‘hides’, from earthwork gun emplacements to barbed wire entanglements, anti-tank ditches and pillboxes. The most substantial of these were the pillboxes, small reinforced concrete or brick buildings of a diversity of shapes and forms, designed to house either infantry, anti-tank guns or field artillery. The full range of defensive structures was generally complementary, however, and a variety of structures were therefore built together, either at vulnerable or strategically important nodal points, along the coast, on the communications network, around vital installations such as airfields, or arranged in linear defensive systems called Stop Lines that were intended to obstruct the enemy's advance.

An auxiliary hide was a Second World War secret base, forming part of Britain’s anti-invasion defences. Sometimes partially underground, they were intended for the use of the British resistance in the eventuality of an invasion. In the event of a German invasion it was intended that saboteurs or resistance fighters should hide at the post and operate behind the invaders' lines.

Despite some later alterations, the World War II auxiliary hide 527m south-west of Chapel Farm is a good example of its type which survives well. The auxiliary hide has seen little disturbance since the Second World War and includes original fittings such as two double-decker bunk beds, a wooden seat, shelves and a water tank. The base is cleverly concealed and well demonstrates a significant aspect of England’s anti-invasion strategy, acting as an operating position for saboteurs following the landing of enemy forces on the south coast.

The auxiliary hide is a rectangular room 2.1m by 2.4m by 4.6m with brick-lined walls and a concrete floor and roof. It is concealed below-ground in the bank of a drain at the edge of a field on Romney Marsh. The hide is entered through 3.7m shafts at either end. The original hatches have been replaced by later cast-iron hatches. The fittings in the interior include two double-decker bunk beds, a wooden seat, shelves and a water tank.
