Seattle City Hall (also known as the Seattle Municipal Building) is the home of the offices of the mayor and city council of Seattle, Washington, located between 4th Avenue and 5th Avenue in the downtown area of the city. Most city departments have their offices in the nearby Seattle Municipal Tower. In 2003, the Seattle city government moved into a new, "green" city hall building. Until 1962, the city government operated from the King County Courthouse, alongside the King County government.{{citation needed|date=June 2017}} The new City Hall and Plaza, together with the adjacent Seattle Municipal Tower, Seattle Justice Center, and (unbuilt) Civic Square, comprise the Seattle Civic Center.
