Any consideration of the Iranian plateau must include the important site of Hasanlu in northern Iran. The Museum carried out excavations from 1956 through 1977. A major aspect of the research focused on the Iron Age settlement. This fortified town was attacked around 800 B.C. The attack and accompanying fire caused the rapid collapse of public buildings. Thus, the site provides a unique opportunity to examine a wide range of objects and materials still in the contexts in which they were stored.
