Unfortunately it’s not in Amsterdam but De Pont, museum of contemporary art is worth the 1,5 hour trip with the train. The building itself is beautiful, it’s a former wool mill but also there collection is worth seeing!
It's a very small museum in the Hermitage about art made by outsiders. It's also known as 'Art Brut', a name given to it in 1972 by French artist Jean Dubuffet. It simply means that it is art made by people that don't fit in the normal life structure that humans suppose to have. Which can mean that the art is made by people who are in jail, who are ill, have a mental dissability or another way of not fitting into the community. The exhibitions are quite small, so it takes you just around an hour. And the hermitage has a nice canal view.
It is in the city centre. This former navy area is now partly open for the public. In summer you can swim in the canal there and have a great view on old Amsterdam, the Scheepvaartmuseum and the dead heart centre of Amsterdam. I like it most in winter, silent, grey, a place to mesmorize, walk alone around, meet a local who is walking his dog, than and have a coffee in pension Homeland, the restaurant hotel there. In central Amsterdam the space is rare, and what is there is overrun with tourists and full of local traffic, the trams, a million bikes, cars and pedestrians. That is why I like this place so much, super quiet space in the centre of Amsterdam.
The fence around De Nederlandsche Bank on the Frederiksplein is a true optical experience. While passing the building, a rhythmic, dynamic pattern appears and disappears in the trellis of the fence. The figures on the sides of the rails were designed in 1992 by artist Peter Struycken, a pioneer in the area of environmental art and generating computer-program based image, light and colour compositions.
