Origins of a Secret Wartime Giant

The Devil's Porridge Museum tells the remarkable story of HM Factory Gretna, established in 1915 as Britain’s largest cordite factory. Conceived in response to a critical shell shortage during World War I, the factory was built rapidly across a nine-mile site straddling the Scotland-England border. At its peak, Gretna employed 30,000 workers, including 12,000 women, who mixed volatile chemicals to produce cordite—the explosive compound dubbed 'the Devil's porridge' by Sir Arthur Conan Doyle. The factory’s scale and secrecy were unprecedented, with operations governed under the Official Secrets Act to protect wartime efforts.

A Community Forged in War

To house the vast workforce, two new townships—Eastriggs and Gretna—were constructed, featuring schools, hospitals, shops, and entertainment venues. The museum highlights this social experiment, including the State Management Scheme which controlled alcohol sales to maintain order among workers. Exhibits recreate workers’ living conditions, such as a typical bedroom and a WWI trench complete with lifelike details. The museum also honors the sacrifices and dangers faced by munitions workers, many of whom suffered injuries or health issues from toxic exposure.

From Humble Beginnings to a Modern Museum

Originating as a small local history display in a church, the museum grew through community passion and volunteer dedication. By 2014, it moved into a purpose-built, state-of-the-art facility in Eastriggs, offering interactive and engaging exhibits that bring the factory’s history vividly to life. The museum houses unique artifacts including a fireless locomotive used to transport cordite safely, a Hawker Hurricane engine, and a memorial to animals that served in wartime.

Exploring the Legacy and Wider Impact

Beyond the factory, the museum explores related local history, including the post-war era and the nearby Chapelcross nuclear power station. It also celebrates the diverse workforce, many from across the British Commonwealth, whose contributions helped shape the war effort and social history. The ongoing Miracle Workers Research Project seeks to uncover untold stories of the 30,000 individuals who worked at Gretna, preserving their legacy for future generations.

An Immersive Educational Experience

Visitors can engage with interactive displays, personal testimonies, and detailed recreations that reveal the human side of industrial wartime production. The museum’s gardens feature a “Dig for Victory” plot, an Anderson shelter, and wartime relics, providing a tangible connection to the era. With a welcoming café and knowledgeable volunteers, the museum offers a comprehensive and moving insight into a hidden chapter of British and Scottish history.

Standing as a Testament to Community and Courage

The Devil’s Porridge Museum exemplifies how local initiative and dedication can preserve vital heritage. It stands not only as a tribute to industrial achievement but also as a memorial to the resilience and spirit of those who labored under difficult and dangerous conditions. The museum continues to grow, fueled by community involvement and ongoing research, ensuring that the story of HM Factory Gretna remains alive and accessible.
