The Conococheague Institute serves as a regional center for developing and fostering awareness, understanding and stewardship of the cultural and natural history of the Appalachian frontier of Pennsylvania, Maryland and Virginia. We strive to achieve our mission through education, research and preservation.


Local people pronounce the Native American word “Conococheague”: CONICA (rhymes with "Monica") JIG (like the Irish dance). In 1822, Conococheague was defined as meaning, “long indeed, very long indeed.”


We are headquartered within Rock Hill Farm, a well-preserved historic farmstead that was established in the early 18th century in southern Franklin County, Pennsylvania, near the village of Welsh Run. Our 30-acre site is listed on the National Register of Historic Places and includes two historic house museums with outbuildings, a research library, two relocated historic log structures, a replica Eastern Woodland Indian village, walking trails with access to a pioneer cemetery, and several historic gardens.
