Oxford Tree-Ring Laboratory - Pennsylvania
Primary Barn Felling Date: Winter 1883/4
Site Master 1712-1883 (oak) BBPAx1 (t = 10.44 DC-AREA2; 9.65 MD2011; 9.59 eapenn).
The Bishop Barn was constructed over the course of several building campaigns. The heart of the building is a traditional Pennsylvania bank barn that is three bays wide. An early granary outshed addition projects from the north elevation, as does the original bank to the upper floor. The cantilevered forebay is extant on the south elevation. Modern additions cover the east and south elevations, obscuring the historic timber-frame barn core.
Dendrochronological analysis has shown that the barn was built from timbers felled in the winter of 1883/4.
