Summary

Alfred Watkins Early British trackways, moats… (1922)

Where a mountain ridge stood in the path of a ley, the surveyor, instead of building a tump on the ridge as a sighting point, often cut a trench at the right angle and in the path of the ley. This shows as a notch against the sky and makes a most efficient sighting point from below. I have counted eight such artificial notches in the mountain ridge when on the road from Llanvihangel Crucorney to Longtown. Each notch can only be seen on the line of sight, and disappears when a quarter of a mile right or left.

It is not easy to realise that many British roads were as ancient to the Roman invaders as the Roman remains are to us.
My general impressions from observed facts are that the Roman surveyors used the sighting system; that they utilized the old trackways, imposing greater width and their far superior road surface and foundations; also that working during the degeneration of the ley system, they did not appreciate the long distance primary points, but working on short distance hills and points their roads are not so consistent and individual.

Earth sighting points were chiefly on higher ground, and now bear the name of tump, tumulus, mound, twt, castle, bury, cairn, garn, tomen, low, barrow, knoll, knap, moat and camp. Another form of earth sighting point was in the form of a notch or cutting in a bank or mountain ridge which had to be crossed by the sighting line.
Water sighting points seem to have evolved from the excavations made for the tumps or moats. Almost all are on low ground, to form a point or ring of reflection from higher ground, and are now known as moats and ponds.
