This volume presents proceedings from the session ‘Monumental Earthen Architecture in Early Societies: Technology and power display’, part of the XVII World UISPP Congress, held in Burgos (Spain), the 4th September 2014. The theme of the symposium is the archaeology of earthen architecture in pre- and protohistoric cultures, with an emphasis on constructive techniques and systems, and diachronic changes in those aspects. The main interest is in monumental architecture (not domestic), where it is better possible to appreciate the building strategies that show raw earth to be as noble a material as stone or wood, but with its very own characteristics which required the development of original solutions and construction techniques. The scope on monumental buildings also allows analyzing the political, social and economical factors that made such architecture a recognized expression of societal values and political power.
