The Pilgrims' Way (also Pilgrim's Way or Pilgrims Way) is the historical route supposedly taken by pilgrims from Winchester in Hampshire, England, to the shrine of Thomas Becket at Canterbury in Kent. This name, of comparatively recent coinage, is applied to a pre-existing ancient trackway dated by archaeological finds to 600–450 BC, but probably in existence since the Stone Age. The prehistoric route followed the "natural causeway" east to west on the southern slopes of the North Downs. The course was dictated by the natural geography: it took advantage of the contours, avoided the sticky clay of the land below but also the thinner, overlying "clay with flints" of the summits. In places a coexisting ridgeway and terrace way can be identified; the route followed would have varied with the season, but it would not drop below the upper line of cultivation. The trackway ran the entire length of the North Downs, leading to and from Folkestone: the pilgrims would have had to turn away from it, north along the valley of the Great Stour near Chilham, to reach Canterbury. History The prehistoric trackway extended further than the present Way, providing a link from the narrowest part of the English Channel to the important religious complexes of Avebury and Stonehenge, in Wiltshire, where it is known as the Harroway. The way then existed as "broad and ill-defined corridors of movement up to half a mile wide" and not as a single, well-defined track. The route was still followed as an artery for through traffic in Roman times, a period of continuous use of more than 3000 years. From Thomas Becket's canonization in 1173, until the dissolution of the monasteries in 1538, his shrine at Canterbury became the most important in the country, indeed "after Rome...the chief shrine in Christendom", and it drew pilgrims from far and wide. Winchester, apart from being an ecclesiastical centre in its own right (the shrine of St Swithin), was an important regional focus and an aggregation point for travellers arriving through the seaports on the south coast. It is "widely accepted" that this was the route taken by Henry II on his pilgrimage of atonement for the death of Bishop Thomas, from France to Canterbury in July 1174, although this has been disputed and some evidence points to his having taken a route via London. Travellers from Winchester to Canterbury naturally used the ancient way,
