For generations the land-seine was the most important tool for catching herring and mackerel, and therefore a suitable casting bay was worth its weight in gold. Goltasundet (the Golta sound) on Golta was such a place. Here the herring often drifted in and fantastic casts might be made here.
At the southern end of the bridge between Radøy and Fosnøy archaeologists found an unusual Stone Age settlement. There was a thick “cultural layer” here with the remains of the waste dumps of a hunting people. The place was called Kotedalen. Here they came, one group after the other, and settled for some weeks, some months, or maybe years before they went on, leaving the settlement deserted. Time after time it happened. At least 16 settlement phases have been identified, stretching over 5,500 years.
