the North Downs trackway in southern England. It is a famous prehistoric route between the English Channel and the chalk heartland of Britain in Wessex and survives as minor roads or as bridle paths in many areas. Both a ridgeway and a lower terrace way beneath the chalk escarpment can be traced. Such tracks shifted seasonally with changing ground conditions. The name, not attested before the 18th century, was given further currency by the poet Hilaire Belloc. In The Old Road (1904), he posited a continuous prehistoric track between Winchester and Canterbury revived by pilgrims journeying to St. Thomas Becket's shrine. Pilgrims possibly did use it, although the London–Canterbury road celebrated earlier by Chaucer was the frequented route. Belloc's “Pilgrims' Way,” however, does not coincide with the prehistoric trackway west of the Hog's Back in Surrey.
