About
The Devil's Porridge Museum tells the extraordinary story of HM Factory Gretna, the world's largest munitions factory built during the First World War. Situated in the village of Eastriggs in Dumfries and Galloway, this accredited museum reveals how a nine-mile factory complex was constructed at astonishing speed across the Solway Plain between 1915 and 1918, employing over 30,000 workers — the great majority of them women drawn from across Britain and Ireland — in the dangerous and vital production of cordite propellant that fuelled the Allied war effort on the Western Front.
The museum takes its vivid name from a phrase coined by the novelist Arthur Conan Doyle, who visited the factory during the war and watched women workers kneading by hand a glistening, volatile paste of gun cotton and nitroglycerine into smooth, rope-like cordite strands. He called it 'the Devil's Porridge', capturing in three words both the hellish danger of the work and its uncanny resemblance to a domestic act. The phrase became the museum's guiding metaphor: the extraordinary made mundane, the dangerous made routine, the industrial made human.
The factory's story began with crisis. In 1915, revelations of a catastrophic ammunition shortage on the Western Front — the Shell Crisis — forced Lloyd George's new Ministry of Munitions to act at an unprecedented scale. The result was HM Factory Gretna, a nine-mile linear industrial city stretching from Mossband to Longtown. At peak production it generated 800 tonnes of cordite per week — roughly a third of all British propellant output. Two purpose-built townships, Gretna and Eastriggs, were created almost overnight to house the workers, complete with canteens, cinemas, hospitals and strictly controlled access points.
The museum's galleries explore every dimension of this remarkable story: the chemistry of cordite production, the daily working conditions of the factory floor, the social world of the townships, the women who dominated the workforce, the constant danger of explosion, and the abrupt human dislocation when peace brought 30,000 redundancies almost overnight. Personal testimonies, archive photographs, original artefacts and immersive displays create a portrait of industrial-scale sacrifice on the home front that is both intellectually compelling and profoundly moving. For anyone interested in women's history, First World War history, Scottish social history or the industrial transformation of the early twentieth century, the Devil's Porridge Museum is essential visiting.

💡 Visitor Tips
- The museum has seasonal opening — always check the website before travelling, especially November through March when hours are significantly reduced.
- Allow at least 90 minutes; the Women of the Factory gallery rewards unhurried attention and careful reading of the personal testimonies.
- Public transport links to Eastriggs are limited — driving is the most practical option, with free on-site parking available.
- The museum is fully wheelchair accessible with hearing loops fitted throughout all main gallery spaces.
- Educational and school group visits are warmly welcomed; contact the education team at least four weeks in advance to arrange tailored workshops.
- Ask at reception for the self-guided heritage trail leaflet — the landscape around Eastriggs still bears faint traces of the former factory buildings and railway lines.
- Combine with a visit to Ruthwell Church, just 5 miles away, to see the 7th-century Ruthwell Cross in its dedicated apse — a remarkable and often overlooked treasure.
- The museum shop has a carefully selected range of First World War books, local history titles and themed gifts that make thoughtful souvenirs.
Highlights
The Devil's Porridge — The Naming of the Factory
The centrepiece display explains the museum's vivid and unforgettable name. When Arthur Conan Doyle visited HM Factory Gretna during the First World War, he watched women workers kneading by hand a glistening, volatile paste of gun cotton and nitroglycerine — the raw cordite propellant that powered Allied artillery shells.
He declared it 'the Devil's Porridge', capturing both the hellish danger and the strange domestic rhythm of the work.
Authentic artefacts, first-person testimonies, original photographs and atmospheric staging bring this remarkable industrial process compellingly to life.
Women of the Factory
Of HM Factory Gretna's 30,000 workers, the great majority were women — many young, working-class and far from home for the first time in their lives. This dedicated gallery honours their contribution through photographs, personal letters, pay books, uniform fragments and recorded oral histories. Conditions were punishing: twelve-hour shifts, skin yellowed by TNT exposure, constant explosion risk.
Yet workers formed robust communities, ran football teams, and built a social world that outlasted the factory. One of the most moving and illuminating galleries in any Scottish museum.
World's Largest Factory — Scale and Ambition
When completed, HM Factory Gretna stretched nine miles from Mossband to Longtown across over 2,000 acres of Solway farmland. At peak production it generated 800 tonnes of cordite propellant per week — roughly a third of all British output. Large-scale maps, architectural drawings, scale models and production statistics convey the extraordinary ambition of an enterprise built at breakneck speed from 1915 under Lloyd George's Ministry of Munitions.
The logistical challenge of housing, feeding and managing 30,000 workers in a remote border landscape was itself a feat of industrial planning.
The Factory Townships — Gretna and Eastriggs
To house its enormous workforce, the government created two purpose-designed townships from almost nothing. Gretna and Eastriggs were planned settlements with canteens, churches, cinemas, sports pitches and strictly controlled access — an unprecedented experiment in state-directed social organisation.
The museum explores daily township life: rationed alcohol, curfews, communal eating and the intense community bonds that formed despite regimentation.
Archive photographs, residents' diaries and personal objects reveal the texture of a world unlike any other, built in months and dissolved within years.
Collections
The Devil's Porridge Museum holds a growing collection of artefacts, archival materials and oral history recordings relating to HM Factory Gretna and its workforce. Holdings include factory uniforms, safety equipment, inert cordite samples, personal correspondence, pay books and a substantial photographic archive assembled from family donations and official sources including the National Records of Scotland.
The museum maintains a reference library of First World War home front materials, contemporary press cuttings, government munitions reports and engineering documents.
As an accredited institution, the collection is catalogued and accessible to researchers by appointment. Temporary loans from national collections enrich the permanent displays, and an active community collecting initiative continues to bring previously unseen photographs and personal stories to light from descendants of Gretna workers across Scotland and beyond.
