Yorkshire is a testament to the enduring power of stone.From the imposing walls of Skipton Castle to the ruins of Whitby Abbey, the inhabitants of England’s largest county have evidently found both beauty and practicality in the use of stone for thousands of years.But amidst these well-known and relatively recent historic sites lies a host of monuments of extreme antiquity, built up to six thousand years ago. Drawing upon new research, excavation notes and diagrams, Yorkshire’s Prehistoric Monuments aims to reveal the secrets of one of Britain's richest archaeological landscapes.Yorkshire's standing stones, burial cairns and extensive earthworks are among Northern Europe's best-preserved prehistoric relics.Featuring original photography and newly illustrated diagrams compiled over several years of travel and writing, Adam Morgan Ibbotson invites you to take a journey into a landscape sculpted by ancient hands.
