One of the largest underground bunker systems of the First World War has been uncovered by archaeologists on a hill in Flanders.
The vast tunnel system is believed to hold the remains of dozens of German soldiers who were entombed in the network when the British launched their attack during the Battle of Messines in 1917.
The bunker, located beneath the village of Wijtschate in Belgium, would have housed up to 300 troops, and at a depth of 20ft would have been shell-proof.
However, the British pummelled the German fortifications on the ridge with millions of shells and it is thought the bombardment caused the timber-lined walls and ceilings around the entrances to collapse, burying men inside alive.
