Oradour-sur-Glane old town

10 June 1944, in retaliation for the sabotage attacks by the French Resistance, the idyllic village of Oradour-sur-Glane was razed to the ground and 642 innocent residents massacred by Waffen-SS soldiers. A new settlement was built post-war but the ruins of the martyred village have been preserved to bear silent witness to the atrocities of war, to serve as a startling reminder of barbarity, to commemorate the dead and ensure that nobody forgets. Each entrance to the ruins bears a notice that say "Remember", and having seen the crumbling walls, wrecked cars, and abandoned houses, you'll be haunted by this image for a long time.
