Great Smoky Mountains National Park strives to Balance Cultural and Natural Values on Federal Lands, which encourages Federal land managers to recognize that cultural and natural values should be considered in an integrated manner to ensure that cultural values are afforded equal consideration. The List of Classified Structures (LCS) is an evaluated inventory of all historic and prehistoric structures that have historical,architectural, and/or engineering significance within parks of the National Park System in which the National Park Service has, or plans to acquire, any legally enforceable interest. The list is evaluated or classified by the National Register of Historic Places criteria. Structures are constructed works that serve some form of human activity and are generally immovable. They include buildings and monuments, dams, millraces and canals,nautical vessels, bridges,tunnels and roads,railroad locomotives,rolling stock and track, stockades and fences,defensive works,temple mounds and kivas, ruins of all structural types that still have integrity as structures, and outdoor sculpture. This map service contains only: Structures are a functional construction made for purposes other than creating shelter, such as a bridge. These resources would include features such as: fortifications, earthworks, roads, fences, canals, dams, engineering features, barns, outbuildings, arsenals, ships, manufacturing facilities, etc. These resources represent sites that do not function primarily as dwellings, however they may serve temporarily to house humans, although their primarily purpose is not a permanent shelter. The point may represent the location of a culvert, while a line may represent a fence or road, and a polygon may represent the circumscribed boundary of a manufacturing plant. Historic buildings are a resource created principally to shelter any form of human activity, such as a house. These resources would include features such as: farmhouses, homesites, mansions, churches, museums (if the building is historic), courthouses, offices, prisons, train depots, etc.Historic buildings most often function primarily as dwellings. The point may represent the center of the building, an entrance, a corner, etc., while the polygon may represent the building footprint. This map service does not currently contain LCS assets that do not fall within the CRGIS definition of a Building or a Structure, however, do note that there may be many other LCS assets in the park that are publicly accessible yet are not classified as a building or a structure and therefore not included in this map service.
