The site of Fort McIntosh is one of the Beaver’s most noteworthy historic treasures. Built in 1778, Fort McIntosh was the first fort of the Continental Army north of the Ohio River. The fort served as the headquarters of the largest army to serve west of the Alleghenies was also the site of the signing of the Treaty of Fort McIntosh of 1785, which opened the northwest and all future U.S. territories to orderly settlement. Between 1784 and 1785, Fort McIntosh was home to the First American Regiment, making it the first permanent peacetime home of the U.S. Army, except for two small detachments at Fort Pitt and West Point. This unit continues today as the Presidential Honor Guard, also known as “The Old Guard”, part of the 3rd Infantry Regiment.
