New York's City Hall is one of the oldest continuously used City Halls in the nation that still houses its original governmental functions. Designed by Joseph François Mangin and John McComb Jr. and completed in 1812, it is one of the finest architectural achievements of its period.
The Landmarks Preservation Commission designated City Hall an individual landmark in 1966 and its central rotunda an interior landmark in 1976. In 1993, the African Burial Ground and the Commons, which includes City Hall and the surrounding park, was designated a Historic District.
The building's rich history, art, and antique collections are documented in the Public Design Commission's Archive, in the Landmarks Preservation Commission's reports, and at the New-York Historical Society.
