Although it has long been believed that the first Celts arrived in Britain around 600BC, some recent scholarship suggests this possibly happened as early as 2000 BC. As a result, a more warlike society evolved which often sacrificed weapons to their gods. The nature of farming changed to less intensive grazing on the uplands. During this period there were many more ceremonial and burial monuments: the stone circles, rows and standing stones or menhirs, and the barrows with their “kist” graves, hollowed out of stone.įrom 1,500 - 600 BC during the Late Bronze Age, the climate became wetter causing movement of the settlements to lowland sites such as Trethellan, Newquay. These metals were found by tin-streaming and open-cast mining. The use of bronze exploited Cornwall’s natural resources of tin and copper. The Early Bronze Age between 2,400 and 1,500BC saw the introduction of metal working.
