This booklet is published as a guide for visitors to the most famous groups of prehistoric monuments in Britain, around Stonehenge and Avebury. The Stonehenge area is described on pages 12-37, and the Avebury district on pages 38 -55, The builders of these sites, and the methods they used, are discussed at the beginning and end (pages 4 11, 56-63).
The dates given are based on the radiocarbon process, which uses the natural radioactivity of plant and animal remains to estimate their age. They must be treated as very rough guides only. The map on this page shows how to reach Stonehenge and Avebury, and there are more detailed maps of the two districts on the back cover.
The drawings by Alan Sorrell give an idea of what the people and their monuments may have looked like in the past; but they must not be taken as authentic reconstructions, since in most cases there is not enough evidence for certainty.
