Dry stone walls, the thousands of miles of stone ribbon stretching across the landscapes of the Scottish Highlands, Yorkshire Dales and Cotswolds, use construction methods which have existed for thousands of years. Indeed, dry stone structures in the Orkney Islands and Ireland are even older than the Egyptian pyramids. A dry stone wall is more than a pile of rocks. It is a carefully built combination of specialized stones, each co-operating with the other to create something useful, strong and attractive. No mortar is used. The wall relies on friction and gravity, and the skill of the builder, to keep it together. The basic building principles are easily learned and this book provides step-by-step instructions to develop the skills to build many different types of wall and structure. With nearly 200 photographs and diagrams.
