The nearby Kröller Müller museum is world famous amongst all because of the Vincent van Gogh paintings. It's located in national park De Hoge Veluwe and Mrs Helene Kröller-Müller intended to build a new really huge art museum. They created a railway into the park (in the 1920s!) to bring all indivually cut bricks from German mountains; mind the carved numbers. Then the 1930s crisis came and the rest is history. Just some stones and 1 wall remind to this story.
