The Tunnellers' Memorial was unveiled in 2010 as a memorial to all the Tunnelling Companies of the First World War and in particular to William Hackett VC. William Hackett was the only tunneller to be awarded the Victoria Cross, after his self sacrifice in repeatedly refusing to leave the side of a colleague, Thomas Collins, who had been trapped by a tunel collapse after the explosion of a German mine in June 1916.
The memorial, carved from Lakeland Slate, is designed to echo the exact measurements of the tunnels beneath - 120cm high by 80cm wide. The circular base is similarly the same size as the access shaft to the tunnels. A capital letter ‘T’ carved out of the memorial represents the Tunnellers' shoulder badge and the view through it points to the exact location where Hackett and Collins still lie. Adjacent is an illustrated explanatory panel describing the work of the Tunnelling Companies.
