Cleveland City Hall is the seat of government for the City of Cleveland, Ohio, and the home of Cleveland City Council and the office of the Mayor of Cleveland. It opened in 1916 and is located at 601 Lakeside Avenue in the Civic Center area of Downtown Cleveland. The building was the first of its kind designed by Cleveland architect J. Milton Dyer for governmental purposes for a major U.S. city. At the time of its construction, City Hall was to continue the city planning of Daniel Burnham's 1903 Group Plan. City Hall stands as a historic landmark that was added to the Cleveland Landmarks Commission.
