Theodolite pillar
Theodolite pillar
It is located on the racing track of the Anglia Karting Centre and dates from the Cold War period, when RAF Pickenham was used as one of 20 Thor missile storage bases. All the Thor launching sites were integrated into the Ordnance Survey grid so as to be able to precisely locate each missile before it was launched. A baseline was surveyed in and marked by a pair of standard OS concrete triangulation pillars installed by the Royal Engineers. The exact siting of the missiles was essential to ensure that the targets were reached and each emplacement had a theodolite shed and a separate long-range theodolite, set on a concrete pillar surrounded by brass survey points.
RAF North Pickenham (USAAF Station 143)

The aerodrome at North Pickenham was constructed in 1943/44 for the use of the United States Army Air Forces (USAAF) Eighth Air Force and designated USAAF Station 143. The first group to move onto the airfield was the 492nd Bombardment Group (Heavy), flying Liberator bomber aircraft. Due to heavy losses the group was transferred in August 1944, and the 491st BG replaced it.

After the war, the airfield was returned to the RAF and it was closed in 1949. In December 1958 however, the station was transferred from Home Command to Bomber Command in preparation for its used as a Thor missile site. After the missile site was dismantled in 1963 the field was closed for good and finally sold off in 1967. See also: Link
