Fort Pitt Site (Point State Park)

The site of Fort Pitt, built by the British in 1758–1761 on the ground where Fort Duquesne had stood. At the confluence of the Allegheny and Monongahela Rivers, it was the largest and most expensive fort the British built in North America. During the Revolution, it served as the Continental Army's western headquarters, supply depot, and the staging point for operations into the Ohio Valley. The fort's outline is preserved in Point State Park, and a reconstructed blockhouse — the only original structure remaining — still stands.
