Founded in 1866, Kunstmuseum Den Haag is one of the best places in the Netherlands to see modern and contemporary art. The sprawling museum houses a collection of about 165,000 works, including pieces from Pablo Picasso, Frank Stella, Egon Schiele, Claude Monet and Edgar Degas. Don’t miss our favourite piece in the museum: Piet Mondrian’s last work, Victory Boogie-Woogie.
