WWI Remains near Ypres, Belgium

WWI began nearly a century ago. They expected a very fast war. They got horrifying attritional warfare. Here are some of the remains (people still find ammunition and those shells still take lives to this day). Pictures of trenches, a fortified machine gun position, what looks like a big pond but is what's left of a major detonation of underground explosives (both sides had their miners dig and then they blew men up by the hundreds from below). Similarly, the pretty, bumpy field is actually bumpy from all the shelling. At the end the war, no trees, no buildings, pretty much nothing was left in this area.
