The stone barn at Best Farm is one of the battlefield's most distinctive historic structures. With its hipped roof, stone construction, and tall opposing front and rear bays, it is markedly different from the Pennsylvania-style forebay banked barns that are common to the region. The stone barn is believed to have originally been constructed as a three-bay threshing barn, and its unusual appearance likely reflects the French heritage of the Vincendière family, who are believed to have constructed it around 1798.
In 2006, in asssociation with the Historic Preservation Training Center and Bucks County Community College, the Monocacy National Battlefield Cultural Resource Division undertook a Historic Structure Assessment Report (HSAR) of the stone barn. This report assessed the overall structural integrity of the barn, and identified treatment alternatives for its long-term preservation and stabilization. As part of the HSAR process, a Level-I HABS drawing and photograph set was completed for the stone barn.
