The Statenkwartier, or States Quarter, is a quarter (Neighborhood) of The Hague, built between 1890 and 1915. Iconic Dutch Art Nouveau architecture. Home to The Hague Art Museum, designed by architect Berlage, hosting the world's most comprehensive collection of De Stijl works, including those of Piet Mondriaan.
