At the Minneapolis Institute of Art
If you ever want to study the History of Art you must come to the MIA. Here they have a perfect example of all the great art in the world. And if I say ALL, I mean ALL. Van Gogh, Rembrandt, Mondriaan, Picasso, Rodin, Greek, roman, Japanese you name it: they have it. And most of the time a very best piece as well.
It was really fun to wonder around and to rediscover some historical perspective. The MIA is huge so even I needed an hour or two to see it all :-)
