Federal Center

This plaza includes Mies' Dirksen Federal Building and Kluczynski Federal Building (built eleven years apart), with a low-rise post office enveloped in their sleek black lines. But the buildings are not quite as famous as the gigantic red constructivist flamingo statue by Alexander Calder in the plaza in front of the post office. An adventurous raccoon may have set a raccoon world climbing record by reaching the scaffolding on the 36th floor in 2006.
