Wasserschloss Raesfeld is a massive castle surrounded by a huge moat. The great thing about this castle is the deer park that has been included in the grounds and makes for a fun day out with the kids.
Deer is not the only type of animal that you are likley to see--the surrounding forest was once used as a hunting ground. This has changed and the area has been filled with a variety of animals that can now call this their haven.
