There were originally over 1,200 such anti-aircraft gun sites built during World War 2, with only about eighty now surviving. This site was rediscovered in 2013 during investigations carried out for Redrow Homes prior to starting house building on the site.

It comprises a light anti-aircraft gun emplacement, a static Bofors 40mm gun, with an attached pillbox. It was built to defend the nearby Royal Ordnance Factory on Euxton Lane.

The site has been preserved and can be accessed via the modern housing estate.
