Beautiful wooden sculpture in castle Amerongen. It reopened after a major renovation. The modern and interactive presentation is nicely done. Perhaps a bit hard to follow for the children though. It's like a theaterical piece but with video presentations on the walls. See http://www.youtube.com/watch?v=1PgUwr3pPjU&feature=youtube_gdata_player for a trailer.
There is no information about the interrior and the interactive guide is far from complete. At the moment I know nothing about this master piece...
