Another model created in Google SketchUp and exported to Trainz with RubyTMIX. Located just north of Stockholm, Sweden, Karlberg Castle is dated back to 1624 when the first stone of the castle was laid by admiral Carl Carlsson Gyllenhielm. 19 years later when he died Magnus Gabriel De la Gardie took over the castle and rebuilt it to the state that it is today. 1688 Karlberg Castle was turned over to the Royal Family. Website in Swedish, with pictures though. Model made by Stefan Larsson.
