Gracie Mansion is the official residence of the Mayor of New York City and is located in Carl Schurz Park, at East End Avenue and Eighty-eighth Street in Manhattan. It overlooks Hell Gate.

Archibald Gracie built Gracie Mansion in 1799. In 1966, a new west wing (the Wagner Wing) was added under the instruction of first lady Susan Wagner.

City Hall is the seat of government of the City of New York. City Hall is located in Lower Manhattan on Murray Street between Broadway and Park Row and across from one of the campuses of Pace University. It faces south to the recently renovated City Hall Park.

At that time of construction, the north end of the city was at City Hall.

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.
