Today, the site of Hill 60 remains a memorial. Because many soldiers' bodies were never recovered from the collapsed tunnels, the ground is considered a cemetery—a silent reminder of the war fought beneath the earth.
By 1917, the British planned a massive offensive at . The strategy involved planting 19 massive deep mines under German lines. The Australian 1st Tunnelling Company, led by Captain Oliver Woodward, was tasked with maintaining and defending two of the most critical mines—the "Hill 60" and "The Caterpillar"—against German counter-mining efforts.

On June 7, 1917, at 3:10 AM, the mines were detonated. The explosion of the 19 mines was so massive it was reportedly heard by the British Prime Minister in London and registered as an earthquake in Switzerland. It remains one of the largest non-nuclear explosions in history, instantly killing approximately 10,000 German soldiers and allowing the Allied infantry to advance with ease.

: Using geophones, tunnellers would listen through the earth for the sound of German picks. If the enemy got too close, they would set off a "camouflet"—a small explosive charge designed to collapse the enemy’s tunnel without breaching the surface. The "Big Bang" The strategy involved planting 19 massive deep mines
: Soldiers worked in pairs on a wooden frame, using their legs to push a spade into the clay. This method was nearly silent, preventing German listeners from detecting their location.
Beneath Hill 60 serves as a tribute to a group of men whose bravery was defined by patience and nerves of steel rather than bayonet charges. It highlights the psychological toll of fighting in total darkness, knowing that at any second, the ceiling could cave in or the enemy could break through the wall.
Hill 60 was not a natural hill, but a massive spoil heap created from the excavation of a nearby railway cutting in the Ypres Salient of Belgium. Its elevation made it a crucial observation post for the German Army.
