Cornwell Farm is a stately home built in 1831 in the Georgian style southeast of Great Falls. The two-story, five-bay brick house was built on the Jackson family farm. The property was called Mine Ridge, then Fairview, and finally Cornwell Farm after B. Franklin Cornwell purchased the property after the Civil War. Before one of the house's interior renovations, signatures of Union soldiers were visible on the home's plaster walls. Traces of the former interior remain in the wood plank floors, exposed hand-hewn beams, and fireplace surround carvings. The mansion now sits on a lot of about 13 acres and is a private home. The house was listed on the National Register in April 1977.
Cornwell Farm is a mansion built in 1831 in the Georgian style southeast of Great Falls along Georgetown Pike, the state's first Scenic Byway. The brick house is two stories tall with 4 chimneys and a hipped roof. The Flemish-bond brickwork on the main, south side of the building is exceptionally well-crafted. The house stands on land that was part of Lord Fairfax's Great Falls Manor. John Jackson had the house constructed on his farm for his daughter, Julia (Mrs. Charles M. Davis). Previously known as Mine Ridge and then Fairview, the name changed to Cornwell Farm after the property was purchased by B. F. Cornwell after the Civil War.
The house had been abandoned for many years when it was purchased by the Pell family in 1936. The interior of the house has undergone extensive renovations a number of times but retains some original details including wood plank floors and fireplace molding. The lower level features the original rough-hewn exposed beams. Cornwell Farm is currently in use as a private, 4-bedroom residence. Before renovations, signatures of Union soldiers from a Civil War-era occupation were visible on the mansion's plaster walls.
Modern development at Cromwell Farm was altered by a local citizens' movement in 1972. As a result, the Yeonas Company developed the property's western 200 acres into residential properties more in line with the area's historic appearance. The historic house was preserved on a lot of about 13 acres and was listed on the National Register in April 1977.
The property was offered for sale in 2013 for nearly 5 million and includes a heated swimming pool, caretaker's cottage with attached greenhouse, four-stall horse barn, and pasture land. Not a bad rate of appreciation - the earliest insurance evaluation found for the home was $1,850.
