Thomas Harrison House, Harrisonburg, Virginia (38.447463, -78.869517)

Main House Felling dates: Spring 1789, Spring 1790

Site Master 1687-1790 (oak) HHHVAx1 (t = 5.80 MATHISTO; 5.47 HQFx2; 5.45 HGFx1). Individual timber 1615-1734 (oak) hhhva8 (t = 6.39 WATCH; 6.18 Allens; 5.96 flpa).

The Thomas Harrison House is a slightly rectangular dwelling that is two bays wide, one bay deep, and one-and-a-half stories high. The house originally had a full English basement, but this has been partially covered by a rise in grade level. The foundations and walls are in coursed rubble limestone with well-defined flat arches over the windows.

Dendrochronological analysis has shown that the Thomas Harrison House was built from timbers felled in the spring of 1789 and the spring of 1790, suggesting that it was constructed after the death of Thomas Harrison, the founder of Harrisonburg.
