Downs in southern England. The Harrow Way (also spelled as "Harroway") is another name for the "Old Way", an ancient trackway in the south of England, dated by archaeological finds to 600–450 BC, but probably in existence since the Stone Age. The "Old Way" ran from Seaton in Devon to Dover, Kent. Later the eastern part of the Harrow Way become known as the Pilgrims Way, following the canonisation of Thomas Beckett and the establishment of a shrine in Canterbury, Kent. This pilgrimage route ran from Winchester, Hampshire, via Farnham, Surrey, to Canterbury Kent. The western section of the Harrow Way ends in Farnham, the eastern in Dover. The Ridgeway similarly keeps to high ground and for at least 5,000 years travellers have used it. The Ridgeway provided a reliable trading route running along chalk hills from the Dorset coast to the Wash in Norfolk. The high dry ground made travel easy and provided a measure of protection by giving traders a commanding view, warning against potential attacks. The Icknield Way follows the chalk escarpment that includes the Berkshire Downs and Chiltern Hills, in southern and eastern England, from Norfolk to Wiltshire. Other examples of historic roads in England include the Long Causeway, a Medieval packhorse route that ran from Sheffield to Hathersage and The Mariners' Way in Devon. The latter was created by sailors in the eighteenth century, or earlier, travelling between the ports of Bideford and Dartmouth, Devon, who linked existing lanes, tracks and footpaths to form a direct route. Scotland In Aberdeenshire, Scotland, ancient tracks include the Causey Mounth, an ancient drovers' road over the coastal fringe of the Grampian Mountains and Elsick Mounth, which was one of the few means of traversing the Grampian Mounth area in prehistoric and medieval times. Roman legions marched along the Elsick Mounth. Roman Britain In Roman Britain, many trackways were built upon by the Romans to form the foundations for their roads. Prior to this, people used trackways to travel between settlements but this was unsuitable for the swift movement of troops and equipment. Mastiles Lane was a Roman marching road and later an important route for monks leading sheep from Fountains Abbey to summer pasture on higher ground. Also known as the Old Monks' Road, this is now a Dales walking track. Ley lines The existence of ley lines and their relationship with ancient trackways was first suggested in
