The documentary Somme: Secret Tunnel Wars is about to start on BBC4 and promises to be a fascinating insight into the archaeology of the war underground on the Somme in 1916.
Part of the programme will apparently feature the Lochnagar Mine Crater, perhaps the most visited British mine crater today on the Western Front. But this was not always so.
In the inter-war period the Somme was visited by hundreds of thousands of battlefield pilgrims, many of whom came to La Boisselle and many of whom visited a mine crater there, but it wasn’t Lochnagar, but the Y Sap Mine Crater. This was a major ‘tourist location’ in the 1920s/30s as it was close to the Albert-Bapaume road and easily accessible from the main road, which Lochnagar was not. However by the 1970s the Y Sap crater was hardly visited and the owner filled it in; leading to Richard Dunning saving the Lochnagar Crater when that too was threatened with the site now preserved by the Friends of Lochnagar.
