Went there today. Got stuck in the mud on the side of the road, but luckily a nice man came and helped us out. The castle is beautiful but there is no entry in, so we just walked around. You have to go up a hill and have no cell service out there, but we went up real quick and took some photos.
My boyfriend is a Freemason who came with me and we're going to try and get in contact with the Mason's who own it now and see if we can get an inside tour next time we're in the area.
