Field archaeology has become a popular pursuit for many people today, when large numbers are enjoying increased leisure time. This book considers a whole range of prehistoric sties that span some 350,000 years from caves occupied in the palaeolithic period to the 'oppida' built immediately before the Roman conquest. The sites are arranged by counties in alphabetical order, and instructions for finding them with National Grid references are given throughout. Location maps and some site plans, together with many photographs, complete a detailed handbook to the wealth of prehistoric field monuments in England.
