Alexander Hamilton lived in a house known as Hamilton Grange, located in the Hamilton Heights neighborhood of Manhattan, New York City. The house was his only owned residence, completed in 1802, just two years before his death in 1804. It was originally situated near present-day 143rd Street but was later moved twice, now residing in St. Nicholas Park. Hamilton Grange was a country home on a 32-acre estate where Hamilton, his wife, and their family resided. He also had a second residence in Lower Manhattan, where the family stayed during winters, while the Grange served as their country estate. The Hamilton family rented a country house in Harlem before owning the Grange. The site is now a historic house museum operated by the National Park Service.
Note that the Alexander Hamilton House in Pennsylvania is unrelated to the Alexander Hamilton who was the founding father and U.S. Secretary of the Treasury.
