Description
The Federal Center contains the Central Post Office, a 45-story Federal Office Building and the 30-story Court House (by Mies van der Rohe, 1964). "Flamingo", a 50ft/16m high metal sculpture by Alexander Calder, sits in the plaza.

The building is an example of International style. It is a relatively unadorned, square, steel-skeleton framed structure.
