Building Features

The Penobscot Building presides over the very heart of Downtown Detroit, at the prominent intersection of Fort and Griswold streets. The flagship address is on the doorstep of dynamic development at Campus Martius, and within walking distance of Compuware Corporation World Headquarters, the Coleman A. Young Municipal Center (City County Building), federal, district and circuit courts and several parking areas. Close proximity to General Motors Global Headquarters, Comerica Park, Ford Field, Joe Louis Arena, and numerous fine hotels, private clubs, restaurants, cultural attractions and casinos provides quick and easy access to the city’s major commercial institutions and entertainment venues.
