An interesting anecdote concerns the explosion of one of the mines on 17 July 1955 by lightning. This mine had not been detonated during the war and was still underground. The explosion created a new crater and reminded the local population of the lasting impact of the war.

The Spanbroekmolen crater, also known as the Pool of Peace, is an impressive mine crater in Wijtschate. This crater was formed on June 7, 1917, during the Second Battle of Messines, when British troops detonated 19 underground mines. The explosion created a crater 27 meters deep and 129 meters in diameter. After nearly 100 years of erosion, the crater is now a peaceful pool 12 meters deep and 76 meters in diameter.

A walking path around it stimulates the observation of the surroundings. Due to the high location (76m) one has a good view. It gives an idea of the view that the Germans had over the battlefield. Various landmarks make the spatial filling of the front landscape interpretable: the position of the Pool of Peace shows the advanced German positions, the first 130m on the other side of the Kruisstraat formed the no man's land.

The mine crater in the grassland on the corner between Wijtschate and Scheerstraat is the result of the explosion of a deep mine from the First World War. Peckham was one of 11 locations on the First World War front where the mine battle was fought. The explosion of 19 deep mines on June 7, 1917 heralded the start of an Allied offensive (third battle of Ypres). The current mine crater at Peckham shows approximately the same dimensions as in 1917 (73m diameter, 14m depth). In 1938, the owner pumped out the crater, with the intention of giving tourists a better view of the original shape of the crater. A journalist testified that the empty crater appeared much larger than when filled. It is unclear how long the crater remained dry. In its natural state, the crater mouth quickly fills with water if it is not continuously pumped empty. (Immovable Heritage Inventory)
