Remnants of a spiral staircase left, I think the supporting bar middle lower left is keeping together what is left of the fire place of the great hall. This is a very shattered castle indeed.
These old broken castles would in my opinion be far better sold off & converted into dwellings where they would be more certan of long term survival and would be better seen as a complete structure. As they are they are surely only ever going to degrade! This would make a fabulous skeleton for a grand design (in keeping of course). As I say just my opinion.
