Mustoe House, located in the Falling Spring Valley in southern Bath County, represents a typical rural dwelling of the early- to mid-19th century in southwest Virginia. It is one of only a few log buildings that survive in the county today. Probably built around 1820 for Anthony Mustoe II, son of pioneer settlers who immigrated from England to Falling Spring Valley in 1792, the house consists of three distinct sections. The original two-story, two-room-plan front section with V-notched corners is attached to a log hyphen connected to another log structure with half-dovetail notched corners. A large exterior limestone chimney projects from the north gable end of the main section. Much of the original interior woodwork survives. The Mustoe House property also contains a log springhouse with half-dovetail notching to the rear of the house. The Mustoe family owned the property until 1942.
