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.
The three-level bunker was first built on compulsory-purchased farmland as an air defence station (an 'R4' Sector Operations Control or SOC) as part of the RAF ROTOR air defence project. [1] Upon the demise of the ROTOR SOC the remaining Nuclear Reporting Cell and UKWMO elements were incorporated into a Home Office 'Regional Seat of Government' or RSG.
The bunker was able to hold various numbers (in the hundreds) of military and civilian personnel, the numbers changing over the years as the role of the building changed from SOC to RSG and, in its later years, 'Regional Government Headquarters' or RGHQ. In the event of a nuclear strike the RSG/RGHQs would be tasked to organise the survival of the population and continue government operations.
The Kelvedon Hatch bunker was built in 1952–53 as part of ROTOR. ROTOR was a programme to improve and harden Britain's air defence network. It was constructed by Peter Lind & Company of London who still trades today. The bunker was a hardened (three level 'R4') Sector Operations Centre (SOC) for RAF Fighter Command. It was to provide command and control of the London Sector of Fighter Command.
From the 1960s to the early 1990s, the UK government (Home Office) maintained the bunker as an emergency regional government defence site. Eventually, in the early 1990s, when nuclear threats in general were seen as diminished, the bunker was sold back to the farming family who had owned the land in the 1950s. It is now a Cold War museum and retains many of its original ROTOR and RSG/RGHQ features.
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.
By 1992, the bunker was no longer required and decommissioned. The land was sold back to the original owners, the Parrish family. [2] It has now been renovated and made into a museum and tourist attraction; many locals appreciate the irony of the many brown tourist road signs in the area, clearly directing people to the "Secret Nuclear Bunker". The BBC TV show Top Gear featured the signs. [3]
The bunker was used as a "Killer's Location" for The Murder Game . Both the living quarters and the operational zone were set up for the "Killer's Game" in the finale. It also played a significant role in an episode of New Tricks titled "The Queen's Speech", first broadcast on BBC One on 20 October 2014.
In 2010, the independent British post-apocalyptic/horror film S.N.U.B! was filmed in the bunker. [4]
The 2016 full-motion video game The Bunker , which uses live-action footage, was fully filmed inside the bunker. [5]
ROTOR was an elaborate air defence radar system built by the British Government in the early 1950s to counter possible attack by Soviet bombers. To get it operational as quickly as possible, it was initially made up primarily of WWII-era systems, notably the original Chain Home radars for the early warning role, and the AMES Type 7 for plotting and interception control. Data from these stations was sent to a network of control stations, mostly built underground, using an extensive telephone and telex network.

It was one of several military installations in the area and covered three dispersed sites.

The Region 6 War Room is a nuclear bunker dating from the early days of the Cold War, on the Whiteknights Park campus of the University of Reading in the English town of Reading. It is one of a number of such Regional War Rooms built during the 1950s and designed to co-ordinate civil defence in the event of an attack on the country using conventional bombs or atom bombs.

In 2019 the built up area had an estimated population of 2,434. The parish had a population of 2,563 in 2001, reducing to 2,541 at the 2011 Census and climbed back up to 2,631 in 2021.
Drakelow Tunnels are a former underground military complex beneath the Blakeshall Estate north of Kidderminster, Worcestershire, covering 285,000 sq ft (26,500 m2), with a total length of around 3.5 miles (5.6 km). They were originally built as a Second World War shadow factory, and were developed during the Cold War to be a fall-back government centre.
Regional seats of government or RSGs were the best known aspect of Britain's civil defence preparations against nuclear war. In fact, however, naming conventions changed over the years as strategies in Whitehall changed.
The British Telecom microwave network was a network of point-to-point microwave radio links in the United Kingdom, operated at first by the General Post Office, and subsequently by its successor BT plc. From the late 1950s to the 1980s it provided a large part of BT's trunk communications capacity, and carried telephone, television and radar signals and digital data, both civil and military. Its use of line-of-sight microwave transmission was particularly important during the Cold War for its resilience against nuclear attack. It was rendered obsolete, at least for normal civilian purposes, by the installation of a national optical fibre communication network with considerably higher reliability and vastly greater capacity.

The Wartime Broadcasting Service is a service of the BBC that is intended to broadcast in the United Kingdom either after a nuclear attack or if conventional bombing destroyed regular BBC facilities in a conventional war. It is unclear if the Wartime Broadcasting Service is still operational as plans are kept mainly secret with the BBC and government officials. According to an article by the BBC, recordings of a nuclear attack warning are still re-recorded and kept up to date periodically.
