A few hours drive North from here is Sweden's largest lake Vänern. On a peninsula there you can find this castle. There has been a castle in some form on this location since the late 13th century. I'm not sure when the current castle was built, but I assume it was somewhere around the 16th or 17th century.
If you're ever near the Southern shores of Lake Vänern or the town of Lidköping it's worth paying a visit to this castle.
