Windmill adapted as machine-gun post Angle · Pembrokeshire · Wales

The Windmill adapted as machine-gun post stands near Angle, in a field east of the B4320 road after the turn north towards the village. It is a former windmill base later reused for military defence.

The original structure was a cylindrical stone windmill tower. The surviving base stands to about five metres and is built of local stone laid in irregular courses. It has a ground-level entrance on the east side. Original upper-level apertures to the north and south have been blocked with masonry; the southern openings have lintels with relieving arches above. The form records the building's origin as a windmill, although the cap, sails, machinery, and upper working structure have gone.

The windmill was probably redundant before its twentieth-century military reuse. Local historical accounts record that it was probably out of use and derelict by 1842. In 1941, after the establishment of Angle Airfield following air raids on Milford Haven, the tower was adapted to serve as a machine-gun post. The surrounding coastal and estuarine landscape formed part of the defensive zone protecting Milford Haven, and the reused tower base became one of the wartime defensive structures associated with Angle.

The building was listed at Grade II on 14 May 1970. Its significance lies in the combined survival of a former windmill base and its later adaptation as a Second World War machine-gun post, a rare layered reuse of a redundant industrial structure within a coastal defence landscape.
