[3] Horseshoe Barracks and various other amenities were added not long afterwards and the site was extended to cover some 200 acres lying between Ness Road and the coast.[4] Alongside its use as a training facility, the ranges were used for experimental trials of guns, rockets and explosives and for the testing of armour and defensive works.[2] As the scale of these experiments began to outgrow the site, its gun emplacements were adapted for seaward firing and it later specialized in coastal artillery training.[2] As early as 1865 the Ordnance Select Committee was recommending the purchase of additional land at Shoeburyness, to accommodate the increasing power and range of artillery then in development.In 1940 the Coast Artillery School was moved from Shoebury to Great Orme, Llandudno,[8] where it remained for the rest of the Second World War, before relocating to Plymouth.[4] Several buildings and structures on the site are listed, including the cart and wagon shed, which is used as a heritage and community centre; together they are described by Historic England as constituting "a complete mid-19th century barracks".
