Oak Hill & The Martha Berry Museum is the home and museum about Berry College founder Martha Berry located in Rome, Georgia. It is also an All-America Selections Display Garden, a part of Berry Schools on the National Register of Historic Places, and a AAA Star Attraction. Oak Hill is a 170-acre (0.69 km2) estate Greek revival mansion. Oak Hill was an original Victorian-style farmhouse that was built in 1847. During the American Civil War and the capture of Rome during The Atlanta Campaign, the estate was used by the Union soldiers as a place to stay. Charles H. Smith, whose widely known pen name was Bill Arp, owned the estate before he sold it to his colleague Andrew M. Sloan. Thomas Berry and his family moved to Rome, Georgia from Alabama in 1868 to become a partner in Berrys and Company, a wholesale grocery and cotton brokerage business. Around 1871, his business became successful, and Thomas Berry decided to move to a better place so he purchased the estate from Sloan for $9,000.
