I'm afraid this place must be abandoned, forgotten. It's falling apart, of course. Plants growing up between the stones aren't a good sign.
The general state of the place is a shame because there are such amazing details here, the carvings around the door and the shaped window openings, the delightful balustrade too.
So what do you make of the jeans? Were they abandoned as well? They could have been. Or, maybe they're just hung up to dry and the place hasn't been forgotten after all.
