One of the finest contemporary art museums in the Netherlands, housed in a former wool-spinning factory from 1902 that was left largely untouched after closure — the long nave-like halls and high clerestory windows were kept exactly as they were. The permanent collection is serious and substantial: Richard Serra's large-scale steel sculptures fill the former machine room, and the upper galleries hold paintings by Marlene Dumas, Sigmar Polke, and On Kawara among others.
Temporary exhibitions are consistently strong, and there is usually something new worth seeing alongside the permanent rooms. The museum is well off the tourist circuit that hits Amsterdam and the Randstad, which means you can often have the Serra hall to yourself on a weekday morning — an experience that's hard to have at any price in a major city.
The building is on Wilhelminapark, about twenty minutes' walk from the station through a pleasant park. Admission is modest by museum standards.
