Modern Cornwall was born in the first millennium. Archaeology points towards a golden age of trade and communication in Cornwall not only between the Celtic communities of the Atlantic Arc but extending as far as the Eastern Mediterranean. This is the era that gave us our Celtic crosses, our saints, the circular “forts” on our hill tops and our holy wells, all of which continue to mark our landscape as distinctively Cornish. This is the era in which the Brythonic languages of Welsh, Cornish and Breton divided into separate entities but retained their family relationships.
