Constructed to protect the coastline of southern and eastern Britain, the forts of the 'Saxon Shore' are among the most impressive surviving monuments of the Roman occupation of the British Isles, although much about them remains a mystery. In an impressive outlay of money, manpower and materials the frontier system stretched from the Wash to the Solent and included the heavy fortification of the major harbours and estuaries of the east and south-east coast. This book explores the history of this frontier system the ruins of which define the British landscape to this day.
