Built in the late 18th century for Joseph Clark, the original frame residence at Willow Grove was substantially enlarged in 1848 by the addition of a brick wing and a unifying Tuscan portico. The remodeling was done for Clark’s son William, who inherited Willow Grove in 1839. The resulting Orange County structure stands as an example of the influence of Thomas Jefferson’s Classical Revival style on the country homes of Piedmont Virginia. The portico is accented by the distinctly Jeffersonian touch of Chinese lattice railings. The house at Willow Grove is enhanced by its pastoral setting and collection of outbuildings. Later the homestead of the Shackelford family, by the end of the 20th century, the house and outbuildings were converted for use as a country inn.
