The primary aim of this volume is to summarize and assess for the first time all available primary evidence for the earliest forms of monumental architecture built within a geographically discrete area of the British Isles - the chalk landscapes of Central South-eastern England. This extremely detailed study includes all the significant mounds, land cuts, flint workings, and monumental architecture (4500-1500 BC) of the South Downs in context, including Blackpatch, Cissbury, and Harrow Hill.
