Manoir Piano is a villa (and some buildings surrounding it) that belonged to a wealthy industrialist. After he died, his daughter inherited the villa. The story goes, however, that she lost her mind and left the villa abandoned.
As to be seen on the photos, the place was pretty trashed already, but it was still impressive to see that a place like this was abandoned. A few weeks after these photos were taken, the villa unfortunately burned down to the ground.
