After an introduction that surveys the history and architecture of Anglesey from prehistory to the end of Middle Ages, this full-colour guidebook presents three tours that together take the visitor to 22 Cadw sites on the island. (Beaumaris Castle is treated in a separate guidebook.) The sites range from the Neolithic burial chambers at Barclodiad y Gawres and Bryn Celli Ddu, through Bronze Age monuments, like the standing stones at Penrhos Feilw, and Roman remains, such as the coastal fortification at Caer Gybi, Holyhead, to the medieval monastic complex at Penmon. Like all Cadw guidebooks, this 48-page book is fully illustrated with a combination of stunning photographs, reconstruction drawings, historical documents, maps and plans
