Description

Second World War Pillbox, Dunster

A Second World War pillbox of no recognised type, built in late 1940 or early 1941 as part of the Somerset Coast defensive line and the Blue Anchor Bay defended locality.

The pillbox is constructed of brick, concrete and stone, with integral camouflage designed to disguise it as a cottage. It features a pitched slate roof with barge boards and stone facing. The building is octagonal in plan, with its entrance positioned in the southern wall and facing north overall.

The structure is shell-proof and equipped with seven steel-shuttered fire-resistant embrasures. Each embrasure has a concrete table beneath the loop with a wide slot to hold a weapon. The interior incorporates a central ricochet wall with unusual deflected cross walls for additional protection.

After the British defeat at Dunkirk in May 1940, the prospect of imminent invasion prompted General Sir Edmund Ironside, Commander-in-Chief Home Forces, to develop an anti-invasion plan centred on a series of static defence lines. These were largely in place by the end of 1940. The Somerset coast was protected by coastal batteries, anti-tank blocks and girders, gun emplacements, cones, section posts and slit trenches, supplemented by large numbers of pillboxes. The Blue Anchor Bay defended locality contained at least twelve pillboxes, an infantry section post, an anti-tank girder and various obstacles.

This pillbox retains its original camouflage, which may have been designed by the theatre designer Oliver Messel (1904-1978) or his successor, the artist Julian Trevelyn, both of whom worked at Headquarters VIII in Taunton at the time. The steel shutters are of an uncommon type. The pillbox forms an integral part of a nationally important defensive landscape and is designated for its rarity as a hybrid type, its historic interest, its uncommon fittings, and its group value within the wider defensive scheme.

Local climate

Wwii Pillbox sits in a wetter-than-average part of the UK, with an average of 1,130 mm of rain a year. This makes it wetter than 88% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 95% of listed buildings.

It experiences an average of 10 freeze-thaw cycles a year, fewer than 90% of listed buildings. Of these, 5 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
