Description
The Anti-aircraft pillbox at Sinfin Central Business Park is a Second World War structure, likely built in the early 1940s. It is considered a very rare variant of a Type 24 pillbox, featuring three octagonal light wells that would have supported an anti-aircraft battery.
Constructed of shuttered reinforced concrete, the pillbox has an irregular hexagonal shape with three linked octagonal wells believed to have housed light anti-aircraft guns. The walls are partially hidden by overburden and vegetation, and the single entrance on the south side, which provided access to both the pillbox and the anti-aircraft wells, has been infilled. The main pillbox section is located to the west, while the cluster of octagonal wells extends from the long rear side of the pillbox to the east.
The pillbox has angled gun embrasures on each of its five outward-facing sides, all currently covered with sheeting. There are also signs of a metal-framed superstructure on the roof, which may have been used to support camouflage netting.
Interior inspection was not possible due to the blocked doorway, but based on details from other Type 24 pillboxes, it is likely that this structure includes interior blast walls and shelves for supporting weapons fired through the embrasures.
