Gwynedd - the north-west quadrant of Wales - is particularly rich in the archaeology of the industrial and modern periods. It was once the major producer of roofing slates worldwide, and for a while it dominated the international trade in copper ore. This is the first comprehensive study of the industrial archaeology of this fascinating region, and takes a wide-ranging view of its scope and nature. The mines, quarries and narrow-gauge railways for which the area is famous are covered in detail, as are well-known works of engineering such as the Menai and Britannia bridges. Also explored are lesser-known industries such as textile production, electricity generation and metal-processing, and other economic activities such as agriculture, which are not generally considered to be part of the industrial landscape. Using a wide range of fascinating evidence, the author tells the remarkable story of the society which evolved in Gwynedd, with its vigorous minority language and its radical politics. The legacies of industrial housing, churches and chapels, along with retailing and consumer goods, are all examined within the broader context of a globalising economy. This attractive volume will appeal to residents and local historians alike. In addition, anyone concerned with emerging issues in archaeology, such as the relationship between documentary, artefact and landscape evidence, the ways of reading the cultural landscape, the regional dimension to worldwide change, and the ways in which we approach the past through its material remains, will find this pioneering study of interest.
