context_page_description: The Kelvedon Hatch Secret Nuclear Bunker at Kelvedon Hatch, in the Borough of Brentwood in the English county of Essex, is a large underground bunker maintained during the Cold War as a potential regional government headquarters. Since being decommissioned in 1992, the bunker has been open to the public as a tourist attraction, with a museum focusing on its Cold War history.
context_section_description: The bunker is built 125 feet (38 m) underground and the entrance is through an ordinary looking bungalow (a standard ROTOR 'Guard House') set amongst trees. The inside of the bungalow leads to a 100-yard-long (91 m) tunnel entering the R4 at its lowest floor (of three). Above are two more floors, the 'hill' which covers it, and a radio mast some distance away.
  The bunker was able to accommodate some hundreds of personnel (the numbers changing as function and form varied over the years) and could sustain them for up to three months. The bunker has air conditioning and heating (using the original ROTOR AC-Plant but replacing the original coolant with a more 'modern' type [c.1980s]), its own water supply (mains water and its own deep bore hole) and generators, and was equipped with many types of radio equipment, protected (EMP) telecommunications, teleprinter (MSX) networks and various military systems: MOULD (system to provide communications between Regular Army, TA Battalions and the Army District and Regional Headquarters) and CONRAD (radio government communications systems post nuclear strike) etc.
