Oxbow says: A detailed study, based on the author's doctoral research, of portal tombs in Ireland, Wales and Cornwall, including a synthesis of previous work on this type of megalithic monument, and original fieldwork. The chapters examine tomb morphology, issues of classification and variants from the 'ideal' portal tomb, finds (lithics, pottery and human bone), and radiocarbon dates. Finally, Kytmannow places the tombs within the context of the landscape, exploring links with other monuments and settlements. Further data, including a catalogue of 225 sites, can be found on a CD.
