HMP Low Moss is located on the outskirts of Bishopbriggs, East Dunbartonshire; near Glasgow, Scotland.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.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.[3] The prison was of wooden, single-storey construction, and the accommodation comprised 11 Nissen hut dormitory-style units linked by internal corridors and Davidson House, a temporary, pre-fabricated building.Though the SPS had been recruiting over the months leading up to the opening, the majority of the staff were to be experienced officers transferring from existing prisons.A Department of Health and Social Security Homeless Resettlement Unit, known as "the Spike" also used part of the former RAF Bishopbriggs site until its closure in March 1996.
