Pair of Second World War pillboxes, A635, Greenfield, Saddleworth Moor

A pair of linked pillboxes were constructed around 1940-1941 as part of the Second World War defences. They are built of orange brick, sandstone, and reinforced concrete and are situated on Saddleworth Moor, alongside the A635 road.

The two pillboxes are rectangular with one angled corner and are linked by an L-shaped passageway that is mostly subterranean. A rectangular roof entrance at the angle of the passageway provides access to both pillboxes. The upper pillbox features an angled northwest corner, two embrasures in the north wall facing the road, and a partial raised upper level on the southwest side with an embrasure facing south, overlooking the passageway entrance. The lower pillbox features an angled northeast corner, with two embrasures facing north and northeast.

The pillboxes are built into the hillside, with only the upper parts visible. The reinforced concrete roofs are partially covered with grass and earth, blending with the surrounding rocks, and have rounded edges. The upper pillboxes are built of orange brick with the visible concrete having rounded edges. The narrow embrasures are splayed and suitable for rifles or light machine guns. Projecting sandstone slabs are above and below the embrasures on the upper pillbox, extending through the width of the brick walls. The lower pillbox has a flush band of sandstone slabs beneath the upper rows of bricks, and projecting sandstone slabs just above ground level on the northern side which also act as embrasure lintels.

Internally, the upper pillbox has a brick platform beneath the raised level, and the stone slabs above the embrasures form lintels while those below act as shelves. The lower pillbox has similar stone lintels and shelves to the embrasures, along with a brick anti-ricochet wall in front of the passageway entrance.

Due to their buried positions, the pillboxes' approximate location is indicated on maps by a circle.
