Barns are the reason the agricultural productivity of south-central Pennsylvania grew and flourished. In addition to establishing the region’s economy, these houses of labor were and in many ways still are part of our cultural heritage. Dianna Heim, author of “Cumberland Valley Barns: Past and Present,” and Phil Schaff, local barn photographer and researcher, explored the many facets of the areas barns, including bank barns: those barns built into the side off a hill (or “bank”) such that both upper and lower levels are accessible at ground level. Heim and Schaff also discussed how development has impacted the farms on which these barns stand.
