This is the Milwaukee Art Museum in Milwaukee Wisconsin. I picked this image because I have personally been here and enjoy the architecture. It is one of the largest museums in the country and contains nearly 25,000 works of art. It is also an architectural landmark. My favorite part is the mechanical wings, which open like a bird at 10am and close / reopen at noon, and then close again at 5pm.
