The Greater Penobscot Building, commonly known as the Penobscot Building, is a Class-A office tower in Downtown Detroit, Michigan. The 1928 Art Deco 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 completion, the Penobscot Building was the eighth-tallest building in the world, the fourth-tallest in America and the tallest outside of New York and Chicago. Rising 566 feet (173 m), the 47-story Penobscot was the tallest building in Michigan from its completion in 1928 until construction of the Renaissance Center hotel tower in 1977. One Detroit Center surpassed the Penobscot as the tallest office building in Detroit upon its completion in 1993. The framing elevation drawing of this building shows a height of 562.166 ft (171.348 m) to the highest roof, approximately 565.75 ft (172.44 m) to the parapet wall around the roof, and 654.166 ft (199.390 m) to the top of the warning beacon atop the antenna.
The Penobscot has 45 above-ground floors and two basement levels, for a total floor count of 47. Although the Penobscot Building has more floors than One Detroit Center (45 above-ground floors compared to 43 for One Detroit), The floors and spires of One Detroit are taller, with its roof sitting roughly 60 ft (18 m) higher than that of the Penobscot.
The building is named for the Penobscot, a Native American tribe from Maine. Native American 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 buildings dedication in 1928:
