About Penobscot Building
The Greater Penobscot Building, commonly known as the Penobscot Building, is a skyscraper in downtown Detroit, Michigan, United States. Rising 566 feet (172.3 m), the 47-story Penobscot was the tallest building in Michigan from its completion in 1928 until the construction of the Renaissance Center's central tower in 1977. The tower has 2 basement floors, and 45 above-ground floors, for a total of 47. The building is located in the heart of the Detroit Financial District. The Penobscot is a hub for the city's wireless Internet zone and fiber-optic network. Upon its completion in 1928, the Penobscot became the eighth-tallest building in the world and the tallest outside New York and Chicago. 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 building's architect, Wirt C. Rowland, also designed such Detroit skyscrapers as the Guardian Building and the Buhl Building in the same decade.
