This mini-mansion in Virginia, USA, is known as the Selma Plantation. It's had a whole host of rich owners down the years, but lost some of its luster after a serious fire several decades ago. The family living there at the time didn't have insurance, so they simply walked away.
Since 2016 it's been owned by someone who plans to refurbish it, but the work hasn't started yet. In the meantime, there are plenty of dusty relics of the past still waiting inside, including a whole grand piano.
