Alvastra Pile-Dwelling

The Alvastra Pile-Dwelling is a prehistoric pile dwelling from ca. 3000 BC located in Alvastra, Ödeshög Municipality, Östergötland County, Sweden. Unique in Northern Europe, it is the only known pile-dwelling site outside the Alpine Pile Dweller culture[1]. The site served as a seasonal social and religious centre for a tribal group that left behind Funnelbeaker culture objects and Pitted Ware culture pottery[1]. Excavations occurred in 1908–19, 1928–39, and 1976–80, with two thirds of the site surveyed by archaeologists[1].
