From the southernmost tip of Cornwall to the far Scottish isles, a wonderful variety of ancient stone monuments still exists in Britain and Ireland, and this book guides the reader to over one hundred of them. Some megalithic sites, like Stonehenge and Newgrange, are well researched and often visited, while others, such as Fernworthy and Bleasdale, are barely known. From stone circles and henges to long barrows and cairns, our distant ancestors adapted and shaped their monuments to all environments, leaving us the tantalizing signs of their long-forgotten lives.
