Eastriggs Munitions Depot, Dumfriesshire

An expanse of land on the Solway Coast was once part of the world's biggest factory.

Later it was a depot forming part of Britain's largest ammunition storage facility, some of which is still in use. This depot was mothballed in 2011.

The nine-mile site was built during World War One. Less than a year into the war, Allied troops on the Western Front faced a shortage of artillery shells. The situation led to what became known as the Shell Crisis of 1915 and the fall of the Asquith government.

A new coalition government set up a Ministry of Munitions to gear the whole economy towards the war effort. HM Factory Gretna, according to Arthur Conan Doyle, was "the newest, the largest, and the most remarkable" of the forty new munitions factories in Britain. Its sole aim was to make cordite propellant, which fired soldiers' bullets and shells.

The complex covered the English-Scottish border from Dornock to Longtown.

Gretna and Eastriggs townships were built by 10,000 Irish navvies to accommodate the over 16,000 mainly female workers who would work shifts in the factories. The dangerous work went on 24 hours a day to ensure a constant supply of munitions to the front line.

Eastriggs was site 3, where the chemical processes took place to make the explosive paste, nicknamed the Devil's Porridge, to be sent to Mossband (site 2) to create cordite.

After the war the sites were sold off, only to be needed again in World War 2 for the storage and distribution of explosives.

Following that war, the Eastriggs facility became part of DSDA (Defence Storage and Distribution Agency) Longtown, housing 63 Explosive Storehouses.

In 2011 the site was mothballed, and the explosive materials transferred to Longtown.

The reception area has buildings dating back to the First World War.

More wartime buildings remain further into the site.

Much of the 25 miles of narrow-gauge railway track was removed in 2016 by a Worksop firm and sold to projects ranging from heritage tourism in London to a sugar cane plantation in Puerto Rico.

Elsewhere more modern buildings remain sealed, with the site left for nature to enjoy.

There's been hope the place could be developed, perhaps as a visitor centre or for nature tourism. However, the remote location and fears about contamination mean that for now, it remains undisturbed.

Shipton ROTOR SOC and RGHQ bunker

Under this bungalow lies a Cold War bunker that has remained under MOD control since it was stripped out in 1993.

It's one of six radar centres set up in 1953 for the ROTOR project. The others were Box, Bawburgh, Goosnargh, Barnton Quarry and Kelvedon Hatch. They used information received from radar stations to direct aircraft and intercept any attack.

In the 60s, following the invention of the atom bomb, it became a headquarters for local authorities to shelter and coordinate action in the event of nuclear war. This one covered Leeds to Teesside.

After the Cold War ended, it fell into disuse, but remains secure and under active surveillance. 

The warning sign at the entrance indicates "HMX Crown Property".

Its current use remains an enigma. 

South Yorkshire and the Cold War

Less than thirty years ago we lived with the threat of nuclear Armageddon. The stand-off between East and West ran from the end of the Second World War to 1991, the year the USSR collapsed. Here's how South Yorkshire fitted into the conflict. 

Soviet targets

RAF Finningley near Doncaster, with its 'V' bomber aircraft, was considered a target for the Soviets. Indeed, nuclear bombs were kept on this airfield in the late 1950s. New Scientist reported in 2001 there was a high accident risk in test flights, as the bombs contained so much fissionable material.

The region's coal mines, roads, rail links and steelworks would have made attractive sites for Moscow, too. Sheffield's Forgemasters manufactured parts for Trident nuclear submarines.

The campaign for peace

Sheffield hosted the World Peace Council's conference in 1950, with Pablo Picasso in attendance. The organisation was set up to encourage disarmament, but the British authorities saw it as 'bogus', undermining it by refusing many delegates' visa applications, and it was never held in Britain again.

That marked the start of South Yorkshire's defiance against the government's nuclear policies. In 1956 Sheffield made a gesture of friendship with a Soviet city, twinning with Stalino (now Donetsk in Ukraine). People set up local CND branches. In 1980 the County Council declared itself 'nuclear free', opposing any hosting or transportation of nuclear materials here.

In 1984 Threads, a docudrama written by Barnsley's Barry Hines (writer of Kestrel for a Knave) was broadcast. It depicted the effects of a nuclear winter in Sheffield, traumatising a generation.

It was fighting in Iran that led to the UK being hit.

South Yorkshire County Council's South Yorkshire and Nuclear War booklet

In December 1983 the government brought in a new law requiring councils to extend civil defence. SYCC's Policy Research Unit was scornful. It published a public information booklet in September 1984, declaring any plans to survive a nuclear attack 'utterly futile'.

The booklet describes what would happen if central government's 1980 'Square Leg' exercise had been real. That study assumed two bombs (250 times bigger than the Hiroshima bomb) would drop in South Yorkshire, one on Eccleshall Road in Sheffield, and one near Finningley airfield near Doncaster.

A blinding flash of light, then a huge fireball as hot as the sun incinerates everything beneath it. Blast winds destroy buildings, sucking up tonnes of dust into a mushroom cloud. At the impact point, each bomb leaves a crater a third of a mile across and 300 feet deep. Cars melt, rivers run dry and people burn. Those in shelters are roasted.

Any survivors bear hideous injuries and burns and face a nuclear winter. The skies are dark with smoke and dust. Chemical smog chokes the atmosphere and temperatures drop to –23°C. Eventually everyone dies. Only insects and grass remain.

The Council considered the Home Office's Square Leg prediction of 190,000 dead (within six weeks) in South Yorkshire an underestimate. It commissioned an independent computer simulation, and concluded 934,000 would die out of 1,292,000 residents.

It described the belief in the need for nuclear weapons as 'absurd', comparing it to a householder blowing their house up to stop being burgled. On the likelyhood of nuclear war, there's no message of hope. It said "every arms race in history has ended in war, and it seems doubtful the nuclear arms race will be an exception".

What remains today

A few remnants of the Government's 'futile' civil defence plans remain. The Royal Observer Corps was set up in the 1950s to monitor the effects of an attack. Hundred of small bunkers were built around the country and you can find examples in Lindholme, Rossington, Abbeydale golf course and elsewhere.

Regional government headquarters were built underground. There's one in Conisbrough, which is now a private house, and there are bunkers under Cusworth Hall and Barnsley County Hall. Doncaster's Emergency Borough Control Centre was on Cleveland Street, underneath the Coroner's Office. It was demolished last year.
