This work investigates the architectural significance and historical function of the Neolithic sites at Windmill Hill and Avebury. Alexander Keiller, a pioneering archaeologist who dedicated his career to the excavation of these monuments, presents a detailed analysis of the earthworks and stone circles. The text serves as a foundational examination of the structural layout and cultural context of these prehistoric sites in Wiltshire, England. By synthesizing his field findings, Keiller establishes a framework for understanding the ritualistic and social purposes of these Neolithic enclosures.

Archaeologists and historians regard this text as a seminal reference for the study of British Neolithic monuments. Readers frequently note the technical density of the prose, which reflects the rigorous field methodology employed by Keiller during the early twentieth century.
