Cetina Valley Survey (CeVaS) is a scientific project whose goal is exploring the prehistoric periods of the Cetina Valley, primarily the Cetina Culture of the Early Bronze Age. Although the project seeks to answer some general questions concerning this important Early Bronze Age culture, such as the settlement pattern, the settlement-tumuli spatial relationship, and overall what kind of society is suggested by the survey, the stress is placed on the relationship with the Aegean. The Cetina Culture is chronologically the earliest evidence of the Aegean contacts with the area of the eastern Adriatic coast. Therefore, a systematic survey of the Cetina Valley is crucial for revealing the nature of the Cetina-Aegean contacts, which in addition can improve our understanding of the earliest Aegean interaction with the central Mediterranean.
