Dunmore’s War.
Fort Hanna’s Town was established in 1774 in Westmoreland County, Pennsylvania, during Dunmore’s War, a conflict between the Colony of Virginia and the Shawnee and Mingo Indian tribes.
Hanna’s Town was a village founded in 1773 along Forbes Road, the main route into the Ohio Country from eastern Pennsylvania. It became the first county seat of Westmoreland County and the first English court West of the Allegheny Mountains. It was named for Robert Hanna, an early settler whose tavern also served as Westmoreland County’s first courthouse.
During Dunmore’s War in 1774, Arthur St. Clair ordered a fort built at Hanna’s Town in preparation for possible Indian attacks. The town became a safe place for travelers, settlers, and those seeking justice and order in the often chaotic western Pennsylvania colonial frontier.
The fort took on added significance during the American Revolution. It became an important center for recruiting militia for the western campaigns against the British in Detroit and their Native American allies. From early in 1776, the fort provided quarters for the regulars of the Eighth Pennsylvania Regiment and other militia companies. It also became a supply depot.
In one of the final battles of the war, Hanna’s Town was attacked and burned on July 13, 1782, by a raiding party of Indians and their British allies. Though the village was rebuilt, it didn’t stand a chance after Forbes Road was rerouted through Newton. The town never recovered, and the county seat moved to Newton, which later became Greensburg in 1786. The old town was then converted to farmland.

In 1969, the Westmoreland County Historical Society investigated the site and found the exact footprint of the old fort. Today, the fort and the town have been reconstructed, including several town buildings, including the Hanna Tavern/Courthouse, three vintage late 18th-century log houses, and the reconstructed fort, blockhouse, and wagon shed. The Westmoreland County Historical Society and the Westmoreland County Parks and Recreation Department maintain and operate the site.
It is located about three miles North of Greensburg, just off Route 119 at 809 Forbes Trail Road in Greensburg, Pennsylvania.
