Germany - Dresden

Old and new -- the dark stone was one of two large sections of wall left standing after the collapse of the church following the Allied firebombing of January 13, 1945, the lighter stone is part of the reconstruction. The sections don't match up, by design: one explanation claims that the mismatch is intended to forever distinguish the old from the new, even after the new stone has weathered to the same black color, and another explanation has it that the mismatch is due to the weight of the rubble pushing on the wall and tilting it out of plumb during and in the decades following the collapse. The mismatch is visible on the interior, as well, where piers flanking the altar are shifted about three inches to one side near their midpoints.
