The site of a Royal Observer Corps monitoring post. The site is located (with all the surface features intact) in a rectangular compound on top of Helsby Hill, in the north west corner of a field. The site was built as part of an extensive network of posts designed to confirm and report hostile aircraft and nuclear attacks on the United Kingdom. At the time of the Defence of Britain survey (1995-2002) the site was found to remain in a fair condition. The site was opened during October 1962 and closed in September 1991.
