The allure of abandoned mansions says a great deal about the power of well-designed architecture: Its beauty will stand the test of time, even when its utility has long worn away. Across the world, these vacated structures continue to attract attention from tourists and locals alike, even as the ivy climbs unrestricted along their facades or sand blows into their deserted interiors. Perhaps it’s the discord between man and nature that makes them so enchanting or simply the eerily preserved reminder of what home once meant for strangers from a bygone era. In either case, they remain hauntingly beautiful. From a rumored haunted in villa in Italy to an entire neighborhood of empty Disney-like castles, these abandoned mansions may have been left behind but will likely never be forgotten.
