The Epirus region of northwestern Greece has witnessed more dramatic changes of physical landscape than almost any other part of Europe. Tectonic activity has shaped a complex and dynamic topography, supplemented by the impact of a local ice sheet formed during the Glacial Maximum, and dramatic episodes of erosion triggered by changes of climate, vegetation and land use. These two volumes set out the history of Palaeolithic occupation over the past 100,000 years, bringing together the full range of studies carried out between 1981 and 1993 as part of the Klithi Project.
