Stirling Hill HAA. This is Stirley Hill near Huddersfield which was the site for two Heavy Anti-Aircraft (HAA) guns during WW2, the top of one concrete bunker is visible in this image. The site is in good condition but is now used by a local farmer for storage. There was a Prisoner of War camp for German and Italian prisoners adjacent but only the foundations are left. The site is also supposed to be haunted!
