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.
Cotswolds
The hills give their name to the Cotswold local-government district, formed on 1 April 1974, which administers over half of the area. Most of the District is in the county of Gloucestershire; some 80% of it is within the Cotswold Area of Outstanding Natural Beauty. The main town is Cirencester and the Cotswold District Council offices are located in that community. The population of the 450 square mile District, primarily in Gloucestershire, was about 83,000 in 2011. The much larger area referred to as the Cotswolds encompasses nearly 800 square miles, over five counties: Gloucestershire, Oxfordshire, Warwickshire, Wiltshire, and Worcestershire. The population of this Area of Outstanding Natural Beauty was 139,000 in 2016.
