A look at Greenwich borough’s “hidden” nuclear bunker

A look at Greenwich borough’s “hidden” nuclear bunker

Tucked away behind New Eltham library lies a Cold War relic many will be unaware of.

For here lies Greenwich Borough Control 51C1 where regional command would have operated in the event of a nuclear war with the Soviet Union.

It survives to this day, though many wouldn’t take a second look at the squat, windowless building located beside a park on Southwood Road.

Woolwich Borough Council opted to locate their centre in New Eltham, and the building was constructed in 1954 with extremely thick concrete walls surrounding numerous rooms and two reinforced blast doors between an air lock. With the merging of boroughs across London in 1965, it became the main Greenwich borough site. It reported to Regional HQ at Chislehurst.

Antenna still visible as are air vents

Inside was a kitchen, men and women’s toilets, plant room, signals room and control room. A diesel generator would provide power and the ability to withstand whatever was outside, at least for a short time.

It seems the centre had a short life as the main borough command of around a decade.

Though in the 1980s a WB1401 receiver was installed which would send an “attack warning red” with the four minute warning message and activate sirens.

The site been mostly empty for around 40 years. It wasn’t just for nuclear war but civic emergencies and disasters. The site was last used to any great degree in 1976 to prepare for flooding under “Excercise Floodprove” before the Thames Barrier opened in 1984 (construction of the Barrier begun two years before the exercise in 1974).

The last known visit was in 2003, and 15 years ago the site was still strewn with paperwork from that exercise.

In 1980 the Greater London Council rendered it unfit for use. The site then planned to move to Peggy Middleton House in Woolwich, yet only finally opened in 1991 as the Cold War ended.

Peggy Middleton House in Woolwich is no more, with a giant Tesco now on site. Yet the bunker in New Eltham lives on, largely unknown. Not much is visible now, with doors solidly blocked. An antenna survives on the roof. It’s now a more pleasant shade of burnt red/brown rather than bare concrete.

The former regional command at Chislehurst is now a luxury home.

A 2003 site visit can be seen here with a brilliant overview of not just this centre, but the entire network.
