National Gallery of Canada, Ottawa
If you are ever near Ottawa, I highly recommend that you visit the National Gallery of Canada which is chockful of art, including an extensive contemporary art collection.
The building itself is worth a visit. From a distance it looks like a huge greenhouse or conservatory. It was designed by Moshe Safdie.
We spent the entire day in the museum and still did not get through all of the galleries. We really enjoyed learning about the Canadian artists, like Tom Thomson, as well as seeing all of the famous works, like those of Rembrant, Klimt, and Warhol.
Our favorite piece was this newly installed one. The whole room, including the mirrored floor, was part of the work, which was suspended from the ceiling.
Up close, it is a construction of mesh wire, and beads, creating a very intricate made-up world.
