About Penobscot Block
The Penobscot Block is a complex of office towers centered around the 45-story Penobscot Building at the corner of Griswold Street and West Fort Street in Downtown Detroit, Michigan. The other two buildings in the complex are the Penobscot Building (youngest of the three), Penobscot Annex, and The Penobscot Building (oldest of the three). The block is occupied by four major buildings: The Penobscot Building (1905, northwest corner along Shelby Street and West Fort Street), Penobscot Building (1928, northeast corner, along Griswold Street and West Fort Street), Penobscot Building Annex (1922, southwest corner, along Shelby Street and West Congress Street), and the Ford Building (southeast corner, along Griswold Street and West Congress Street). The block is also bordered to the west (along Shelby Street) by 607 Shelby Street, which holds the Peoples Savings Bank Building (also known as the Peoples State Bank). The buildings on the block are named for the Penobscot, a Native American tribe from Maine. This complex contains a gross total of 1,008,000 square feet (93,600 m) of office and retail space.
