The Andrew Carnegie Mansion is a historic house and a museum building at 2 East 91st Street, along the east side of Fifth Avenue, on the Upper East Side of Manhattan in New York City. The three-and-a-half story, brick and stone mansion was designed by Babb, Cook & Willard in the Georgian Revival style. Completed in 1902 for the industrialist Andrew Carnegie, his wife Louise, and their only child Margaret, it served as the family's residence until 1946. Since 1976, the house has been occupied by the Cooper-Hewitt Museum, part of the Smithsonian Institution. The mansion is internally connected to two townhouses at 9 East 90th Street and 11 East 90th Street, both of which are part of the Cooper-Hewitt.

Fleetwood Park was a 19th-century harness racing (trotting) track in what is now the Morrisania section of the Bronx in New York, United States. The races held there were a popular form of entertainment, drawing crowds as large as 10,000 from the surrounding area. The one-mile (1.6 km) course described an unusual shape, with four turns in one direction and one in the other. For the last five years of operation, Fleetwood was part of trotting's Grand Circuit, one travel guide calling it "the most famous trotting track in the country".
