A site is defined as "the location of a significant event, a prehistoric or historic occupation or activity, or a building or structure, whether standing, ruined, or vanished, where the location itself possesses historic, cultural, or archaeological value, and there are several different types of sites in Georgia.
Historic sites are places where an event or activity took place but where there were no buildings or structures associated with the event or activity, or where the associated buildings or structures no longer exist. Historic sites are important primarily for the events or activities that took place there, although significant archaeological resources also may be present. Historic sites may have distinctive natural features, such as a mountain or cave or tree, or they may simply be the place where something important happened, such as an open field where a military engagement took place. The most commonly recognized type of historic site in Georgia is the battlefield.
