The past couple of decades have seen a growing interest in historical research of the built environment. The symposium discusses the importance and role of such research to the broad field of Environment-Behaviour Studies (EBS). It also discusses recent theoretical and methodological issues within this area of research. The focus of the symposium is on the following themes: a- Why should we study the history of the built environment? b- What do we expect from such studies? c- What are the theoretical and methodological tools available for historical research of the built environment? d- What are the theoretical and methodological deficiencies/problems? e- What could be done to enhance theoretical and methodological development in historical research of the built environment which is relevant to EBS?
