The Greater Penobscot Building, commonly known as the Penobscot Building, [a] is a 45-story office skyscraper in downtown Detroit, Michigan. [4] Constructed between 1927 and 1928, the Art Deco building is located in the heart of the Detroit Financial District.
The Greater Penobscot Building stands 566 feet (173 m) tall, [b] and was the tallest building in Detroit and in Michigan from its completion until 1977, when it was surpassed by the Renaissance Center. At the time of its completion, it was the eighth-tallest building in the world, the fourth-tallest in the United States, [5] and the tallest in the United States outside of New York and Chicago. [6] [7]
It is part of the Penobscot Block, which also contains the original Penobscot Building and the Penobscot Building Annex.

The building is named for the Penobscot River in Maine. The building was named by Simon J. Murphy, President of the Simon J. Murphy Company. Murphy named the building from his association with lumbering in the Maine woods and on the Penobscot River in Maine. [8] Motifs in art deco style ornamentation is used on the exterior and the interiors. The following version of the choice of the name of the building is found in an undated publication believed to have been published concurrent with the building's dedication in 1928:[ citation needed ]
On holidays, both the Penobscot Building and the nearby One Woodward Avenue light-up for the night, with red, white and blue for Independence Day and Canada Day; and red, white and green for the Christmas season. In addition, during the Christmas season, the Penobscot Building's radio broadcast tower is illuminated bright gold, to resemble a giant glowing Christmas tree topped with a flashing red beacon. The Penobscot Building has become a souvenir item along with other Detroit skyscrapers. [9]
The first televisions in Michigan were sold in the retail space on the Griswold level of this building.[ citation needed ]
For a period of time in the late 1970s and early 1980s, it was renamed the City National Bank Building, after its major tenant. When City National was acquired by another bank and renamed, the historic Penobscot name was revived.
In May 2012, the Penobscot Building was sold for $5 million to the Toronto-based real estate company, Triple Properties Detroit. [10] [11] The building has since incurred numerous fines and code violations from the city of Detroit. [12] [13] [14] [15] [16]
The architect Wirt C. Rowland, of the prominent Smith Hinchman & Grylls firm based in Detroit, designed the Penobscot in an elaborate Art Deco style in 1928. Clad in Indiana Limestone with a granite base, it rises like a sheer cliff for thirty stories, then has a series of setbacks culminating in a red neon beacon tower. Like many of the city's other Roaring Twenties buildings, it displays Art Deco influences, including its "H" shape (designed to allow maximum sunlight into the building) and the sculptural setbacks that cause the upper floors to progressively "erode".
The opulent Penobscot is one of many buildings in Detroit that features architectural sculpture by Corrado Parducci. The ornamentation includes American Indian motifs, particularly in the entrance archway and in metalwork found in the lobby. At night, the building's upper floors are lit in floodlight fashion, topped with a red sphere.
The building's architect, Wirt C. Rowland, also designed other Detroit skyscrapers, such as the Guardian Building and the Buhl Building, in the same decade.
The tower is also connected to two older and smaller buildings, the 1905 Penobscot Building and the Penobscot Building Annex (1916). Together, the buildings comprise the Penobscot Block, located at Griswold Street and West Fort Street. The Greater Penobscot was the last portion of the complex to be developed.
The Penobscot Building is a contributing property in the Detroit Financial Historic District, and on the National Register of Historic Places.
