Earthen Construction Technology presents the papers from Session IV-5 of the 18th UISPP World Congress (Paris, June 2018). The archaeological study of earthen construction has until now focused on typology and conservation, rather than on its anthropological importance. Earth is the permanent building material of humankind, and was used by the world’s earliest civilizations for their first urban programmes. The architectural and engineering know-how required to carry out these monumental achievements can only be obtained through archaeological research: extensive excavations with attention to architectural and structural features, and their collapse, coupled with typological, mineralogical, micromorphological, botanical, chemical, and mechanical studies of building materials. This line of research is recent, starting in the 1980s in Europe, but is rapidly growing and illustrated in this volume.

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.
