Seasonal migration was a feature of life, as with many other hunter-gatherer communities. Pitted Ware communities in Eastern Sweden probably spent most of the year at their main village on the coast, making seasonal forays inland to hunt for pigs and fur-bearing animals and to engage in exchange with farming communities in the interior. This type of seasonal interaction may explain the unique Alvastra Pile Dwelling in south-western Östergötland, which belongs to the Pitted Ware culture as far as the pottery is concerned, but to the Funnelbeaker culture in tools and weapons.
