VikingHedeby is at its height. It encompasses an area of around 24 hectares and has a population of approximately 1,500 people.
VikingHedeby is sacked by Polabian Slavs, after already having been sacked by Harald Hardrada of Norway a few years before. Residents relocate to Schleswig, and Hedeby's role as mercantile center ceases.
The Viking trading center of Hedeby is made a UNESCO World Heritage Site in 2018: the "Archaeological Border complex of Hedeby and the Danevirke".
