Located 20 metres below the pavements of Arras lies Wellington Quarry. In November 1916, the British started preparing for the 1917 spring offensive. New Zealand tunnellers connected up the town’s chalk extraction tunnels to create a real network of underground barracks large enough to accommodate 24,000 soldiers. The Quarry preserved the memory of those thousands of soldiers quartered underground just a few metres from the front, before launching themselves onto the field of battle on 9th April 1917.
