The Grove was built around 1857 by Colonel John Preston, when he retired after 32 years as presiding judge of Washington County. This was the second “manor” house built on the Walnut Grove Plantation.  The original “Walnut Grove” is located about a quarter mile distant, and was constructed by John Preston’s father, Col. Robert Preston, the first land surveyor of Washington County. The style of the house suggests that Colonel Preston followed new architectural trends of the day in the design of his retirement home. The Grove is a two-story brick Greek Revival house with Italianate features, located on the outskirts of the city of Bristol, and featuring a wood-framed porch. Though extensively vandalized after its sale by Preston family heirs in 1972, the house was carefully and extensively rehabilitated to house new offices of the Children’s Advocacy Center of Bristol/Washington County at Preston’s Grove.
