In the documentary you can also enjoy the moving beautiful yards. “They are truly unique worldwide,” says Van den Boogaard. “I think the best thing is that you have different levels. You can sail on the water, you can walk on the wharf quay; then you can also walk along the water for long distances, and of course you can walk on the street. So you have three levels and there are also all kinds of trees on it. You can do it in different ways and that is a very rich picture.”
