The Doughnut
"The Doughnut" is the nickname given to the headquarters of the Government Communications Headquarters (GCHQ), a British cryptography and intelligence agency. It is located on a site in Benhall, in the suburbs of Cheltenham, Gloucestershire, in South West England. The Doughnut houses 5,500 employees; GCHQ is the largest single employer in Gloucestershire. Built to modernise and consolidate GCHQ's multiple buildings in Cheltenham, The Doughnut was completed in 2003, and GCHQ moved into the building in 2004. It is the largest building constructed for secret intelligence operations outside the United States. The Doughnut was too small for the number of staff at its completion, and a second building in a secret and undisclosed location in the 'Gloucestershire area' now also accommodates staff from GCHQ. The Doughnut is surrounded by car and bicycle parking in concentric rings, and well protected by security.
Glevum
Glevum (or, more formally, Colonia Nervia Glevensium, or occasionally "Glouvia") was a Roman fort in Roman Britain that became a "colonia" of retired legionaries in AD 97. Today, it is known as Gloucester, located in the English county of Gloucestershire. The name Glevum is taken by many present-day businesses in the area and also by the 26-mile "Glevum Way", a long-distance footpath or recreational walk encircling modern Gloucester.Glevum was established around AD 48 at an important crossing of the River Severn and near to the Fosse Way, the early front line after the Roman invasion of Britain and which became one of the most important Roman roads in Britain. Initially, a Roman fort was established at Kingsholm. Twenty years later, a larger replacement fortress was built on slightly higher ground nearby, centred on Gloucester Cross, and a civilian settlement grew around it. The Roman Legion based here was the Legio II Augusta as they prepared to invade Roman Wales between 66 and 74 AD, later being based at Burrium (Usk) and then Isca Augusta (Caerleon) in South Wales.
