Cadillac Place in Detroit

This grandiose structure in the New Center area is now called Cadillac Place.  Built by Albert Kahn and completed in 1923, it used to be GM's headquarters until 2001. Outside of New York City, it was the largest office building in the world. Its 31 elevators whisk people to their upper floor offices.  Today it houses lots of government agencies that represent the state of Michigan. Pedestrian overhead walkways connect it to New Center One and the Hotel St Regis across West Grand Boulevard.
