Barr Castle
"Barr Castle in Lochwinnoch is a 15th century keep overlooking Barr Loch, rising to four storeys, which was altered in the 16th century (and probably later, too). The gables of the castle have collapsed, apart from the chimney stack which juts up into the sky. Not much survives of the former courtyrad of the castle. The main hall was on the first floor, reached by a turnpike stair, which continued to the rooms on the upper floors."
