The Devils Porridge Travel Guide

The Devil's Porridge Museum stands on the outskirts of Eastriggs, marking the site of HM Factory Gretna, once the world's largest munitions factory. Constructed in just nine months during 1915-1916, the factory was a monumental response to the shell crisis of World War I. Spanning nine miles along the Scotland-England border, it employed around 30,000 workers, including 12,000 women who became known as the 'munitionettes.' The factory produced cordite, a highly volatile explosive mixture nicknamed 'Devil's Porridge' by Sir Arthur Conan Doyle, who wrote about the hazardous process of mixing nitroglycerine and gun cotton.

The museum vividly portrays the daily realities of the workforce. Workers lived in hastily built wooden huts and brick houses within the newly created townships of Gretna and Eastriggs, designed following Garden City principles. The museum recreates a worker's bedroom and a First World War trench to immerse visitors in the era. It details the strict working conditions, health risks—including chemical exposure that discolored workers’ skin and damaged teeth—and the social controls imposed, such as pub restrictions to curb disorder. Entertainment venues like dance halls and cinemas provided rare relief from the intense labor.

Beyond industrial history, the museum honors the human stories behind the factory. It highlights the diverse origins of the workforce, many of whom traveled from across the UK and the Commonwealth, reflected in Eastriggs’ nickname as the ‘Commonwealth Village.’ The Miracle Workers Research Project, based at the museum, continues to uncover personal histories, including those of women’s football teams and individual workers, enriching the narrative of this vital wartime community.

The museum's displays include a restored Mossband Clock from the factory’s headquarters, a fireless locomotive named Sir James used to transport explosives safely, and a 'Dig for Victory' garden featuring an Anderson shelter and a Hawker Hurricane engine. The second floor explores World War II history and the region’s later nuclear power station at Chapelcross, linking the site’s industrial heritage to broader technological developments.

Though the factory itself was dismantled after the war, the museum preserves its legacy and educates about the sacrifices and achievements of its workers. The surrounding townships remain as living reminders of this extraordinary industrial and social experiment. The museum’s modern, purpose-built facility, opened in the 1990s, is a testament to community dedication, transforming a once-forgotten wartime site into a place of remembrance and learning.

The museum actively involves volunteers in historical research, supporting both local and remote contributors in uncovering untold stories. This ongoing work culminates in exhibitions and films that deepen public understanding of the factory’s role and the people who made it possible, ensuring the Devil’s Porridge legacy endures for future generations.
