Tumbling Down

The walls on this building have been tumbling down  for years. maybe decades, or longer. 
I am not sure if it is an old castle or just a grand house, all I know is that I pass it every day on the way drive in to work.
It is situated between NP and New Deer. The sign at the end of the road reads, 'Milton of Federate.'

This was the 2nd musical act I saw. Yesterday's was the support act.
