An excellent brief guide to the current understanding of Stonehenge, copiously illustrated with maps, photographs and a few artistic reconstructions. As well as describing the process of construction of the monument over a period of about a thousand years, it also explains other monuments in the surrounding landscape and details the history of the archaeological exploration of the site, with changing understanding of when it was built.
I read this following my visit and it wonderfully supplemented the numerous information boards around the site and in the visitor centre. A highly recommended souvenir. ( )
