The Main Branch is the headquarters of the Detroit Public Library System in Detroit, Michigan. It is located in Detroit's Midtown neighborhood, between Woodward Avenue and Cass Avenue.
Designed by Cass Gilbert, the Main Branch was constructed with Vermont marble and serpentine Italian marble trim in an Italian Renaissance style. His son, Cass Gilbert Jr. was a partner with Francis Keally in the design of the library's additional wings added in 1963. Among his other buildings, Cass Gilbert designed the United States Supreme Court Building in Washington, D.C., the Minnesota State Capitol and the Woolworth Building in New York City.
