Behind the scenes at a Cold War relic
Rare opening for Greenham Decontamination Suite
A THOUSAND people gathered to see first-hand a hidden Cold War artefact at Greenham Common.
Greenham Control Tower volunteers, with permission from Greenham Trust, opened the Decontamination Suite within Building 274 to unprecedented public interest at Greenham Business Park.
Free guided tours led by local history experts ran at the weekend from 11am to 4pm.
The theme of the Heritage Open Days this year was Astounding Inventions.
With East-West diplomatic tensions rising, in June 1980 the decision was made to store ground-launched cruise missiles at the USAF airbase RAF Greenham Common. The first missiles arrived in November 1983.
By 1986, 96 missiles were stored at the base, only two miles away from the populations of Newbury and Thatcham.
This development warranted the construction of specialised storage and control facilities, including the Decontamination Suite and Ground Alert and Maintenance Area (GAMA).
The Decontamination Suite, completed in 1985, served as the command centre for the USAF 501st Tactical Missile Wing between 1982 and 1991.
The wing was responsible for coordinating the deployment of missiles in the event of a Soviet attack.
The building was constructed to withstand biological and chemical, though not nuclear, warfare.
Visitors explored the same eerie, claustrophobic circuit as contaminated soldiers would have undergone.
Each room is secured with thick reinforced concrete walls and ceilings and sealed with blast-proof steel doors weighing several tonnes.
First, visitors entered the room where the contaminated would remove their respirators.
Still wearing their uniforms, the soldiers then showered, cleaned their weapons and doused themselves with Fuller’s earth, a skin decontaminant used to treat exposure to chemical agents.
They proceeded to shower properly and dispose of their uniforms, which were sent for incineration.
The tour ended with the Plant Room, an area self-sufficient in air, water and sanitation.
In the event of a napalm attack, the entire site could survive on a six-hour supply of emergency oxygen.
Fortunately, the suite never witnessed combat.
The Intermediate-Range Nuclear Forces Treaty signed by the US and USSR in December 1987 led to the withdrawal of cruise missiles from Greenham Common by mid-1991 and the base closed for good in 1992.
Building 274 has been privately owned and used for secure data storage since 2014. The nearby GAMA silos have also been owned by a private company since 2003.
Both are classified as scheduled monuments, meaning they are protected from future development or demolition.
The Decontamination Suite is still sometimes used for military training exercises.
Activities offered at the control tower were also well attended, including talks, tours and walks around the common, while the café had one of its busiest weekends.
Visitors also enjoyed a concert performed by East Woodhay Silver Band.
Control tower volunteer coordinator Pam Hart thanked volunteers for their hard work, saying “it made such a difference”.
