Until the early eighteenth century, life for the majority of people in Ireland had not changed greatly since the Middle Ages, but then the pace of change began to accelerate. New sources of power heralded the Industrial Revolution in Britain, although Ireland's economy continued to be largely agriculture-based. However, a better transport system was needed to enable more efficient movement of goods and materials. This was provided by the civil engineers who planned, designed and built the canals, improved the existing roads, developed the railways, and extended the harbours. They also provided water supplies for the growing centres of population and systems for the disposal of wastewater required for improvements in public health. Fully illustrated throughout, the book is an important contribution to the industrial history of Ireland and describes the achievements of such famous names as Alexander Nimmo, Sir John Macneill, Bindon Blood Stoney and John Killaly. It includes a gazetteer of many surviving historical civil engineering works, ranging from bridges, aqueducts and viaducts, to canals, dams and water supplies, and from docks and harbours to lighthouses.
