HMP Low Moss is located on the outskirts of Bishopbriggs, East Dunbartonshire; near Glasgow, Scotland. It has been operated by the Scottish Prison Service as a prison since 1968 and was for low-category prisoners who had sentences of less than 36 months to serve. The original establishment was closed in May 2007, with the entire site being cleared and redeveloped with a considerably enlarged footprint. The new prison was reopened in March 2012, and accepted its first intake in almost five years. Karen Norrie is the Establishment's Governor. History RAF Bishopbriggs Originally a Second World War-era Royal Air Force (RAF) Barrage balloon depot, known as RAF Bishopbriggs, constructed in 1939, base of No.18 (Balloon) Squadron and No. 15 Maintenance Unit. It was also used as an overnight 'transit' camp for other RAF Units being transferred from the south of England to the north of Scotland. After WW2, RAF Bishopbriggs was utilised as a training school for the Royal Military Police for a time. RAF 388 Mobile Radar Bomb Scoring Signals Unit In the 1960s the Officers Mess building on the other side of the Lenzie road, next to St Mungo's playing fields, was later used for the Combined Messing (Officers, SNCOs and other ranks) and Unit HQ base for 388 Signals Unit (RAF), also known as 388MRBSSU or the Glasgow bomb plot. It used two AA No. 3 Mk.7 radars to score simulated bombing missions on pre-determined target ranges in the Glasgow area. The radars were installed on one of the concrete former Barrage Balloon pans, situated near the Civil defence practice house and were enclosed by a fence and locked gates. The unit closed in mid 1966 and the radars moved to RAF Ouston in Northumberland. USAF and RAF bombers utilised the range, types included the Douglas B-66 Destroyer, Convair B-58 Hustler, the V bombers and English Electric Canberras. Scottish Prison Service use Low Moss was first used by the Scottish Prison Service as a training school between 1964 and 1970. There was a break in this use between 1966 and 1968 when training reverted to Barlinnie Prison. Conversion to Prison In September 1968, the former RAF camp was initially converted into a temporary, low security male prison. The planning permission restricted the sentence length and category of prisoner, and it set an eventual closure date of the temporary prison for December 1974. An extension of time until 1986
