New Windsor Cantonment breathes life into the onetime Continental Army post housing 7,500 soldiers and 500 women and children civilian war refugees. A small but talented staff authentically dressed and equipped as soldiers or soldiers' wives demonstrate the work and pastimes of life in a military community from weapons drill, woodworking, blacksmithing, medicine, cooking and laundry to celebrations and funerals, sports and games, and aspects of ordinary life in extraordinary times 60 miles above British-controlled New York City at the close of the Revolutionary War. Two new galleries introduce guests to the forgotten people behind the famous figures, and to a lost historic site nearby where the seeds of victory at the Siege of Yorktown were planted through intensive training. One original log hut and several recreated buildings provide a backdrop for living history presentations and programs, with plans for additional outdoor work areas and structures to widen the scope of the human story and to interpret the economic and political crisis that reached a head here in 1783. In 2006 the National Purple Heart Hall of Honor was established here to collect and share the stories of men and women wounded in combat in American military service. The Purple Heart was preceded by the Badge of Military Merit established by George Washington in 1782 and in 1932 over 100 World War I veterans received some of the first Purple Hearts 150 years later here in 1932.

After the army disbanded and the nearly 600 buildings were auctioned off in 1783 by General Washington's orders, the newly deforested grounds served as farmland and a dairy through much of the 20th century. A small section of land surrounding a centennial monument was opened by New York state in 1918. Following a 1932 celebration, the National Temple Hill association was founded in 1933 to acquire more land and develop the historic site, a movement which finally gained momentum in the 1950s and 60s only to face financial difficulties. New York State purchased the 120 acres, buildings and collections and today works with the volunteers of the National Temple Hill Association to interpret this and nearly 300 acres of land owned by the Town of New Windsor as a living museum of the final winter post of Washington's northern Continental Army.
