"Workers were recently removing invasive plants during a dune restoration project at a park in Knokke, Belgium, when they struck concrete just inches beneath the ground's surface. Further excavations revealed three German bunkers from World War II that had been buried after the conflict ended in 1945. Alongside the bunkers, archaeologists unearthed two brick trenches, a water well, and part of a concrete path as well as utensils, cables, and ammunition from the war. After measuring and documenting the finds, researchers covered them with sand once more to preserve them for the future."
