This thesis presents the stratigraphic evidence for occupation from the later part of the Late Bronze Age (Late Helladic IIIC middle) to the beginning of the Early Iron Age (Sub-Mycenaean and Early Protogeometric period) at the archaeological site of Kynos, which is situated on the western shore of the North Euboean Gulf in mainland Greece. In particular, the architectural remains and their related pottery sequence, as well as the distribution of finds, are under discussion in order to understand the overall organisation of the site and the main activities of its inhabitants. A fresh examination compares the data to the latest material and archaeological evidence from other contemporary sites in the Greek region in an attempt to shed further light on the social structure at Kynos and to illustrate the distinctive characteristics of the periods under discussion.
