Roper's Knob Fortifications were constructed by Union Army forces between February and May 1863 in Franklin, Tennessee. According to Tennessee Archaeology, "Roper's Knob served as part of a chain of signal stations that provided a communications link from Franklin to Murfreesboro. Additionally the knob had a large redoubt capable of holding four large artillery pieces, a blockhouse, cisterns, and a magazine...." The area was investigated by an archeological dig in 2000.
