WWII Ruin, Hamm Westfalen, Germany

A five-story World War II bunker pockmarked by several air attacks but structurally sound provided a vertical, urban plot with great views for a residential penthouse built on top of it in 2008. As a historical landmark, the bunker remains unpainted and unchanged in stark contrast to the contemporary brick, wood and steel dwelling with cantilevered decks on top.
