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.
