From trench 122 near the Ploegsteert forest, two 18-metre-deep mines were dug during the 1st World War. The explosives from these were detonated simultaneously with 18 other deep mines on 7 June 1917. The sound of the explosions could be heard as far away as London.
The two craters are still visible in the landscape today. Crater Ultimo, to the left of the road, is lined with trees. The wall of the also water-filled crater Factory Farm, to the right of the road, is visible as a raised berm in the meadow. Both craters are not freely accessible.
