Alvastra pile-dwelling

The Alvastra pile-dwelling is a unique archaeological site located in Östergötland County, Sweden, dating back to approximately 3000 BCE. This stilt house served as a seasonal social and religious center for a tribe, reflecting the influences of the Funnelbeaker and Pitted Ware cultures. The construction involved two phases over 18 years, separated by a 22-year hiatus, and the final structure covered an area of 1000 square meters. Despite its communal nature, the site was not fortified, suggesting its use was more ceremonial than defensive. In the later phase, it was converted into a cemetery. The site's significance lies in its distinctive architectural style and its role in the cultural and ritual activities of the Neolithic and Chalcolithic periods in Northern Europe.
