The Big Dig
Each house, both old and a new one in Staunton downtown is built in similar old style with brick sidewalks in front of them and historic lights in gardens and along streets. I asked about it in Wilson Museum and I've got to know that the city maintains strict building codes in the historic downtown area so that the area can be used for period films.
The city project known locally as the Big Dig in which all of the modern utilities were put underground to hide them started in 1990'. I am not surprised that the historic downtown area of Staunton was used in the American Civil War film Gods and Generals. The local Shenandoah Valley Railroad was used in filming of Hearts in Atlantis.
