Systematic archaeological excavations have taken place at Petersburg National Battlefield since the 1970s.  These archaeological investigations aid the National Park Service in interpreting the battlefield, as well manage all of the
historic, cultural, and natural resources located on the battlefield.  These projects have been undertaken by the
National Park Service and their various contractors.  Sites ranging from prehistoric periods through the Siege of
Petersburg have been excavated.  Both domestic and military sites are present on the battlefield and several of both
types have been studied.
