(Shawnee State Park)
(1758), near Schellsburg
A British encampment on the Forbes Road.
Fort Bedford (Park)

(1758 - 1770's, 1794), Bedford
Originally called Fort Raystown during its first year. This was a palisaded stockade with five bastions covering 7000 square yards, with two outer redoubts on the south and west. Surrounded by the river and an eight-foot deep moat, the British thought it was impregnable. It was said to have been the first British fort ever to be captured by American rebels, when in 1769 18 colonials captured it by obtaining admission through a ruse. They were protesting trade with the Indians. The fort was not active during the American Revolution. The current blockhouse structure is a reproduction (1958), used as the visitor center/museum, which features a scale model of the fort. An original stone building still exists on the grounds. It was used as President Washington's headquarters on his march against the instigators of the Whiskey Rebellion in 1794. Admission fee. The town was originally known as Raystown, first settled in 1751.Another website

(1756 - 1765), Fort Loudon
Built by the PA colonial militia on the site of settler Matthew Patton's burned house. It was a 127-foot square palisade with two wooden buildings on stone foundations, and a stone-lined well. This was an important supply depot on the Forbes Road in 1758. Known as Fort Conococheague in some accounts. In 1765 about 300 settlers forced the British to evacuate the fort, angry that trade with the Indians was resumed after Pontiac's War. Excavations were undertaken in 1977 and 1982 to determine the exact location and layout of the fort. The palisade trace and the stone foundations were located. The fort's stockade was reconstructed in 1993 on the exact site, but without the interior buildings at present. The visitor center is in a restored 1798 house that was originally built on the fort site, but was relocated to its present site in 1982. Located one mile southeast of town on North Brooklyn Road. The spelling of the town's name was later altered. Another website
