Constructed in 1790 by William Douglas Meriweather this barn originally contained a new threshing machine that Thomas Jefferson wrote about visiting in 1796. More than two centuries later this barn still stands as a testament to how well is was built and is the oldest standing barn in Albemarle County.

In 2016 careful restorations were made to the barn. Modern materials were removed to expose original pegged timber floors, the original roof framing was reconstructed, reclaimed pine siding installed and stone foundations were repaired. Craig Jacobs, a master of old buildings, executed the restoration work and brought a wealth of vintage materials and vintage construction know-how to preserve the most architecturally significant barn in Albemarle County.
