This book presents the work of the Finnish project SYGIS on Jebel Bishri, a mountainous region in Central Syria. The main focus of this archaeological project was to unambiguously locate discovered sites on the Earths surface in order to provide a starting point for the recording and creation of data to help with the cultural heritage management of Syria, as well as to help prevent looting and to aid in the preservation of cultural remains in this vulnerable area. The sites encountered during this project covered a time span of nearly 0.5 million years and in a series of chronological chapters the development of human cultures in the Jebel Bishri region over the course of time is explored. The interaction of people between different environmental zones and the cultural longue dur??e emerge as themes of particular importance.This report presents the work of the Finnish Jebel Bishri project, which surveys and maps the sites of visible human activity in this mountainous region of eastern Syria by remote sensing and field walking.
