Eildon Hill lies just south of Melrose, Scotland in the Scottish Borders, overlooking the town. The name is usually pluralised into "the Eildons" or "Eildon Hills", because of its triple peak. The 422 metres (1,385 ft) high eminence overlooks Teviotdale to the South. The north hilltop is surrounded by over 5 km (3.1 mi) of ramparts, enclosing an area of about 16 ha (40 acres) in which at least 300 level platforms have been cut into the rock to provide bases for turf or timber-walled houses, forming one of the largest hill forts known in Scotland. A Roman army signalling station was later constructed on the same site as this hill fort.

National scenic area (NSA) is a conservation designation used in Scotland, and administered by NatureScot on behalf of the Scottish Government. The designation's purpose is to identify areas of exceptional scenery and to protect them from inappropriate development. There are currently 40 national scenic areas (NSAs) in Scotland, covering 13% of the land area of Scotland. The areas protected by the designation are considered to represent the type of scenic beauty "popularly associated with Scotland and for which it is renowned". As such they tend to be mainly found in remote and mountainous areas, with a review in 1997 noting a potential weakness of national scenic areas was that the original selection placed undue emphasis on mountainous parts of the country. National scenic areas do however also cover seascapes, with approximately 26% of the total area protected by the designation being marine. The designation is primarily concerned with scenic qualities, although designated national scenic areas may well have other special qualities, for example related to culture, history, archaeology, geology or wildlife. Areas with such qualities may be protected by other designations that overlap with the NSA designation.
