The MAK (Museum of Applied Arts) has a fantastic exhibit running until Sept. 27 focusing on its collection on Van Cleef & Arpels jewelry. The exhibit juxtaposes pieces from the MAK's permanent collection with the jewelry in a labyrinth-like setting. I cannot stop thinking about it. https://www.mak.at/en/program/exhibitions/glanzstuecke
The MAK also has excellent permanent collections (Thonet chairs, Klimt anyone?) and other rotating exhibits. For example, check out the Barbara Pflaum photography exhibit.
I took some photos during my visit which are on my instagram account - @3point14maker - if you want to see some of my favorite pieces.
