Conococheague Institute

The Conococheague Institute is located on historic Rock Hill Farm near the village of Welsh Run, Franklin County, Pennsylvania–about halfway between the Boroughs of Greencastle and Mercersburg.
Established in 1994 as a non-profit corporation, the Institute maintains five historic buildings, a 6,000 volume research and genealogy library, and more than 20 acres of scenic trails/woodlands. It is part of a network of sites belonging to the Colonel Washington Frontier Forts Association, all dedicated to promoting and interpreting the history of the French and Indian War in Pennsylvania, Maryland, West Virginia and Virginia. Other regional members of this Association include Fort Loudoun in Franklin County, Pennsylvania; the Jonathan Hager House in Hagerstown, Maryland; Fort Frederick State Park in Big Pool, Maryland, Fort Edwards in Capon Bridge, West Virginia; Abram’s Delight Museum in Winchester, Virginia; and Fort Necessity National Battlefield in Farmington, Pennsylvania.
