Its inner fort and retrenchment lines are rebuilt, with archaeology guiding the reconstruction.","why_significant":"The fort was the last of a series of fortifications built along the Forbes Road during the 1758 British campaign against Fort Duquesne. It withstood a major French and Indian attack in October 1758, which the nomination says contributed to the French abandonment of Fort Duquesne. The archaeological collection of French and Indian War artifacts is described as the most complete of its kind.","narrative":"Reconstructed on its original ground in Ligonier, Westmoreland County, Fort Ligonier is a British fort of the French and Indian War. It was the last in a chain of fortifications built along the Forbes Road in 1758 to protect supply lines during General John Forbes's campaign against Fort Duquesne. Originally called the Camp at Loyal Hanna and briefly Pittsborough, it was renamed for Field Marshal Sir John Ligonier after the French abandoned Fort Duquesne in November 1758. The fort held out against a major French and Indian attack in October 1758, a defense that contributed to the French withdrawal and gave the British control of the Forks of the Ohio. Garrisons remained until the fort was decommissioned in 1766. Reconstruction began in 1947 using documentary research and archaeology, including excavations by Jacob L. Grimm from 1960 to 1965. The rebuilt stockade, bastions, gates and log buildings are regarded as highly accurate. Its artifact collection is considered the most complete of French and Indian War material.","period_of_significance":"1758-1759","architect_builder":"Charles M.
