Death leaves an imprint. It may be physical, that is, human remains of people that died or were killed in a certain place or artifacts that mark where there was human activity at some point in time but no longer. Those artifacts can be the actual instruments of killing, everyday items used by those no longer present or simply a reminder that the place was once inhabited. Those “presences”, the dead lying underground and or the objects, contribute to making the place a sort of hallowed ground; a place that witnessed life and pain; the extinguishing of thousands or millions of flames of men, women and children, like when you’re in a cemetery, which is very eerie indeed. The sites of battles, mass killings or memorials to the dead, literally thousands that litter the global landscape, are exceptionally intriguing places. Here are the eeriest memorials in the world.
