Art and Nature Project De Nollen
Art and Nature Project De Nollen is an initiative of the late sculptorist R.W. van de Wint. Van de Wint started a painting art experiment in the old inner dune area De Nollen. This develloped into a 'complete artwork' of murals, sculptures and buildings. De Nollen is a continuous project. Visitors will be guided on a walk along steel sculptures and monumental buildings half hidden in the landscape.
Entering these buildings through narrow passages. Inside you'll find oil murals. King Mother Princess Beatrix is a well known admiror of this sculpturist. It is said that that's why she opened the completely renovated area "Duinpark" as a queen. You'll find lampposts and a bridge made by Van de Wint here. (Nieuw Den Helder)
