Lieutenant Colonel Roger Morris built it, and it is now a city-owned house museum.","why_significant":"The form calls it the only important pre-Revolutionary house still standing in Manhattan and the major surviving landmark of the Battle of Harlem Heights. George Washington used it as his headquarters from September 14 to October 18, 1776. It is also noted as a fine example of Colonial Georgian architecture, with later Federal-style changes made by Stephen Jumel in 1810.","narrative":"Perched on Harlem Heights in Manhattan, this two-and-a-half story Georgian house was completed around 1765 for Lieutenant Colonel Roger Morris, who first called it Mount Morris. It has a full portico with four Doric columns, a rusticated wooden exterior imitating stonework, and a rear octagonal wing. In September 1776 General George Washington made it his headquarters, shortly before and after the Battle of Harlem Heights, where American forces pushed back the British and regained confidence after earlier defeats. After the war the house served for a time as a tavern, then was bought in 1810 by the merchant Stephen Jumel, who restored it in the Federal style. Saved from demolition when New York City bought it in 1903, it has operated as a house museum, with rooms furnished in the styles of its different periods. It is described as the only important pre-Revolutionary house still standing in Manhattan.","period_of_significance":"1700-1799","architect_builder":"Built by Lt. Col.
