Nick Dixon - Crannogs and other sorts of artificial islands in Scottish lochs can be considered by their nature being surrounded by water, as fortresses. However, underwater excavations have demonstrated a massive amount about the way of life of their inhabitants. Clear evidence for farming, hunting and gathering show that the crannog dwellers were sophisticated farmers and exploited the landscape around them for a varied food supply. The evidence for Homestead or Fortress will be explored in this talk. Dr. Dixon is the Research Director of the Scottish Crannog Centre at Kenmore and an expert diver.
