The Phaiakians in the Odyssey was a seafaring trading nation. They lived on the island Östergarnsholm close to Gotland in a prehistoric fortress. There are more such embankments on Gotland, and Visby the main town may originally have been a trading post and fortress from the Bronze Age. In the center of the city there has been found a settlement from the older Stone Age, 3300-2800 BC. The older Visby is enclosed by a 3600 meter long ring wall which had 29 towers, and 27 of them are preserved until today. It is one of the largest ring walls in Europe.

Similar strongholds as on Gotland can be seen 150 kilometers to the east in Latvia, among others Mezite, Satezetes Pilskalns and Tervetes Pilskalns. Pilskalns means town-height and ancient hilltop. The entire coastal land from the Gulf of Riga to the peninsula of Sambia in the Curonian Bay, were the original homeland Courland for the Curonians or Kurs. South of Samland is the lakeside landscape Ermland.
