Rock Ford Plantation is the 17th-century home of Edward Hand. He purchased the 177 acres in two portions, in 1785 and 1792, and added a Georgian-style brick mansion circa 1794. Rock Ford's four floors conform to the same plan—a center hall and four corner rooms—typical of the period, and the original 18th-century floors, rails, shutters, doors, cupboards, paneling, and windowpanes remain. Furnishings were selected based on Hand's own estate inventory. During Hand's life, the property served as a tenant farm with fields, livestock, and orchards. Today, Rock Ford is one of the most important examples of Georgian domestic architecture surviving in Pennsylvania and the most intact building predating 1800 in Lancaster County.

The plantation offers living history interpretation, hands-on activities, open-hearth cooking demonstrations, guided tours, educational programs for specific grade levels, and a pre-visit education packet.
