Fort Allen (Westmoreland County, Pennsylvania)

Fort Allen (also known as "Truby's Blockhouse") was a military structure which was built in Hempfield Township, Westmoreland County in the Province of Pennsylvania by Colonel Christopher Truby of Pennsylvania's colonial militia. Erected in 1774 in response to a threatened attack by Indians upon German pioneers who had settled in the area, it became a frontier fort of Dunmore's War in 1774, and also was used as a fort during the American Revolution in which Truby also served as an officer with the Continental Army.
