In accordance with guidelines set forth by the Centers for Disease Control, the Pennsylvania Department of Health, and the office of Gov. Wolf, we have decided to immediately close the Conococheague Institute’s site at Rock Hill Farm. This closure will remain in effect until further directives are issued indicating safe conditions for reopening tourism sites in our area.

This decision was made after much discussion and with thoughtful consideration for the health and wellbeing of our valued members, visitors, staff, and the community we share. We apologize for any disappointment and inconvenience.

During these uncertain times, we hope we can all draw on the best of human qualities. Please reject rumors and follow the advice of medical leaders to protect you and your families and neighbors.

Remain calm and vigilant, and we can all get through this together. During this closure, communication is an important part of coping. We will be communicating with you about any changes.

Please visit our website: for updates, plus a wealth of archived photos and reference materials. There is a link to become member or to renew your membership with CI and much more. We will also be regularly posting on our Facebook page. And as always, you may also renew your membership by mailing a check payable to “Conococheague Institute”. Our various membership levels are detailed on the website.

Please note: during our closure there is ABSOLUTELY NO BUILDING ACCESS, INCLUDING OUR OFFICE.

Thank you for your understanding. We hope to all be together soon and we wish you good health.

Walk Back in Time

The Conococheague Institute is a hands-on regional learning center. 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, walking trails with access to a pioneer cemetery, and several historic gardens.

Our Mission

The mission of the Conococheague Institute is to develop and foster awareness, understanding and stewardship of the cultural and natural history of the Appalachian frontier of Pennsylvania, Maryland and Virginia. The Institute strives to achieve our mission through education, research and preservation.
