 Among the museum's holdings is the Old Stone House, a Georgian two-story structure built in 1766 near present-day Granite Quarry by Michael Braun, a wheelwright, printer and carpenter.The house is the oldest in Rowan County and one of the State's few remaining stone houses.Descendants or Braun and the Fisher family worked to preserve the house in the 1950s, when there was the possibility of it being torn down so its rock could be used for roads.
