Fisher Body Plant No. 21 opened in 1919 in Detroit’s Milwaukee Junction neighborhood, which would soon become one of the most important manufacturing sectors in America. General Motors soon took a large stake in the company, limiting its production to mostly Buick and Cadillac automobiles. The plant later produced aircraft components during World War II and remained in use until GM vacated the building in 1985, with other businesses operating there into the 1990s. The city took ownership of the property in 2000 following tax foreclosure and, after sitting vacant for decades and becoming one of Detroit’s most well-known abandoned buildings for urban exploration and years of stalled plans, it is now being redeveloped into a mixed-use residential project.
