The Walking Dead is a very small world
Rick’s group of survivors have traveled all over the place over the six seasons so far, but The Walking Dead hasn’t strayed too far from where it began in Georgia. The show has done a great deal of filming in and around the town of Sequoia. In fact, Sequoia served as Woodbury during the Governor’s reign in Season 3, and Alexandria is set right next to it. The prison from Seasons 3 and 4 was only about a mile from where Hershel’s farm was located, and the destroyed prison was redressed to serve as the construction site outside of Alexandria.
