The Cratère de Lochnagar, an impressive war memorial, was created by a huge mine blown up by the British Royal Engineers on 1 July 1916, as part of the Battle of the Somme. The explosion marked the beginning of the battle and left a crater 90 metres in diameter and 25 metres deep. Interestingly, the crater was named after Lochnagar Street, the trench from which the tunnel was dug. The crater is now a preserved site of remembrance and a religious service is held there every year on 1 July in memory of those who died.

The 38th Welsh Division Memorial, unveiled in 1987, is dedicated to the soldiers of the 38th Welsh Division who fell at the Battle of Mametz Wood in July 1916, at the start of the Battle of the Somme, and "marks their sacrifice for Freedom" with a red dragon, the symbol of Wales. With its wings in motion, the dragon, facing Mametz Wood, tears through barbed wire with its claws. On July 10, 1916, during the Battle of the Somme, the 38th Welsh Division was forced to capture Mametz Wood, a stronghold of German resistance that was preventing any eastward advance of the British Army. The wood was taken after fierce bayonet fighting, at the cost of very heavy losses, on July 12, 1916. For most of the soldiers, it was their baptism of fire: 4,000 men were put out of action, including 600 killed and 600 missing. Having lost a quarter of its strength, the 38th Welsh Division was relieved after a week and did not participate in a major offensive again until July 31, 1917.
