Unfortunately it is only a ruin, but thanks to some information boards you can get a good overview of where exactly what used to be. The special thing about this castle is that it actually had two outer baileys. The western and the eastern outer bailey. In the area of the former western outer bailey there is now a war memorial. In the area of the former eastern outer bailey there is an open area with a few benches.
