Icknield Way is a very ancient trackway that runs north east to south west across England for 110 miles, from Knettishall Heath in Norfolk to Ivinghoe Beacon in Buckinghamshire. The Icknield Way claims to be the oldest road in Britain, consisting of prehistoric pathways, already ancient by the time the Romans invaded. Most parts of the way are still accesible as tracks and green lanes running along the chalk escarpment that runs through the Berkshire Downs and Chiltern Hills. There are many field monuments and ancient sites along the route.
