Impressive and imposing, Cadillac Place dominates a full city block in central Detroit. Formerly known as the General Motors Building, the Cadillac Place was renamed after the french founder of Detroit, Antoine Laumet De La Mothe, Sieur De Cadillac. Today, it’s the destination for more than 2,000 State of Michigan employees, who swarm in and out of its noble bronze doors each weekday.
