Washington's Headquarters State Historic Site
Visit Washington's Headquarters located at 84 Liberty Street, Newburgh, NY 12551 in Orange County. Visit Washington's Headquarters, the "nation's first publicly owned historic site and tour the rooms where American history was made. In the critical months that General George Washington spent at Newburgh, he made some of his most important contributions to shaping the American republic. It was here that Washington rejected the idea that he should be king after the war; ended the Newburgh conspiracy, preventing military control of the government; created and awarded the Badge of Military Merit, forerunner of the Purple Heart; and circulated a letter to State Governors that influenced the writing of the Constitution."

Knox's Headquarters State Historic Site
