An interesting little book spoilt by some basic errors that should not have got past a good editor. For example, on p. 8 it is stated that Boudicca sacked Winchester, on p. 43 the author speculates that the inhabitants of Din Lligwy might have watched the sunset over an east-facing bay and on p. 80 it is suggested that the rock carvings in Barclodiad Y Gawres burial chamber comprise the finest collection of rock art in Britain. The map of the sites covered is very poorly reproduced.
The CADW guide (ISBN 1-85760-142-4), although older, is cheaper and has better illustrations.
