About The Devils Porridge Museum

Nestled just 7 miles from the Anglo-Scottish Border, The Devil’s Porridge Museum is dedicated to telling the story of how this once quiet area flourished into a hub of wartime activity.

The Devil’s Porridge Museum has grown over the past 20 years with the local community at it’s very heart. From a small exhibition in St John’s Church and via a large uninsulated industrial shed in Eastriggs the Devil’s Porridge has been transformed into a fantastic modern interactive museum in the township.

The Devil’s Porridge Museum has therefore been on an incredible journey to become the purpose-built interactive museum it is today.

Our dedicated team of staff and knowledgeable volunteers have played a vital role in helping to build this wonderful museum which ensures that the story of HM Factory Gretna can be told for years to come.

Our unique name is inspired by Sir Arthur Conan Doyle, the author of the Sherlock Holmes series, who while visiting the factory as a war correspondent witnessed the munitions girls mixing the guncotton by hand and commented on the girls kneading the explosive mixture, ‘into a sort of Devil’s Porridge’.


Our museum is fully accessible, with disabled parking, accessible toilets, a lift for our first floor exhibits and wheelchairs available if needed. Service animals are accepted, but no pets please.

We also have a defibrillator installed outside our building, which is 24hr accessible. A code for the defibrillator can be given by staff during opening hours of the museum or the emergency services via a 999 call.
