Jutting out some thirty miles into the Irish Sea, from the western edge of Snowdonia, the Llŷn Peninsula, in north-west Wales, is renowned for its stunning beaches and countryside, with much of its landscape designated as an Area of Outstanding Natural Beauty. The peninsula is also home to a remarkable and abundant collection of archaeological sites and monuments, some of national importance, which bear witness to the ancient societies who once inhabited this narrow finger of land on the western fringe of Britain.This abundantly illustrated book examines this rich corpus of archaeological evidence, beginning with the faint but fascinating traces that Mesolithic hunter-gatherers have left in the landscape of the Llŷn Peninsula and ending in the early medieval period, with about 9,000 years of human habitation thus covered in its pages. In the course of the book, we will encounter a wealth of fascinating archaeological evidence, which includes impressive megalithic tombs and an axe ‘factory’ from the Neolithic; burial mounds and mysterious standing stones from the Early Bronze Age; rural settlements and magnificent hillforts occupied in the Iron Age and Romano–British period; and memorial stones erected by early Christian communities.Much more besides will be found in the pages of this volume, which throws considerable light on the ancient peoples of the Llŷn Peninsula, and the rich archaeological heritage of this special part of the United Kingdom, which has much to offer those who are interested in the distant lives of our ancestors.
