Fort Duquesne

Fort Duquesne was a French fort built in 1754 at the forks of the Ohio River, where the Allegheny and Monongahela rivers meet, on the site of present-day Pittsburgh. Its seizure from Virginian builders helped start the French and Indian War. The French blew it up and abandoned it in November 1758 as a British army under John Forbes approached, and the British built Fort Pitt on the site.
