It is a well-known fact that this region went through quite an intricate prehistory, so much so that it is difficult to move about amongst the muddle of peoples that have followed each other. The impact of two influences, however, remains clear: the Europeans coming from the North-West – for example, the Proto-Celtic peoples of Beaker culture (bearers of the dolmens culture, recently discovered in this island and dating back to the neolithic Bronze Age), and the Mediterranean influence with a clear oriental matrix. Complex urban settlements become increasingly evident from around 1300 BC.
