5) Château de la Mothe-Chandeniers, France
This crumbling castle west of Paris has sections which date back to the 13th century, other which are more modern. The tragic story of this amazing chateau is that it was restored in 1932, only to fall subject to a fire which made it unlivable. For decades this fairy tale castle has been sitting empty, becoming over grown. But, recently a group of concerned internet citizens collectively bough the chateau together to save it from ruin.
