Castle Duurstede (Kasteel Duurstede)
Castle Duurstede (wijk bij Duurstede, NL) is again more a ruin than a whole castle but still nicely preserved. I has a tower witch is very interesting on the inside. The Castle tower, build in 1270, has very thinck walls and small corriders. Spiral stairs take you to old rooms witch till this day look awesome.
The castle is surrounded by water en a little park. It is not very big but certainly worth visiting.
