New York City Hall, on Murray Street between Broadway and Park Row, is the seat of government of the City of New York. City Hall houses the mayor's office and the New York City Council. The New York City Hall building was designed by John McComb, Jr. and Joseph François Mangin. Construction of the City Hall building began in 1803 and was completed in 1812. The building's front facade is marble and granite, while the back is sandstone. The building's distinctive cupola has served as a model for spires on other buildings, notably Eliot House at Harvard University.
City Hall was designated a landmark by the New York City Landmarks Preservation Commission in 1966. The interior was designated in 1976. (Designation List 64)
