The Doughnut

The Doughnut is the nickname given to the headquarters of the Government Communications Headquarters , a British cryptography and intelligence agency. It is located on a 71 hectares 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, with GCHQ staff moving in the same year, and fully moved into the building in 2004. It is the largest building constructed for secret intelligence operations outside the United States.
