The field research at Groß ottenhagen (Berezovka) conducted in 2003 and 2004 was the first

international scientific collaboration between German and russian archaeologists in kaliningrad

region since 1945. The Groß ottenhagen cemetery demonstrates almost continuous functioning

for about 1,000 years, from the roman iron Age up to the middle Ages. The part of the site considered

in the article belongs to the last stage of the development of sambian-natangian culture

among the old Prussians in the 11th to the 13th centuries Ad. despite a first analysis by the

excavators in 2005, this data from the cemetery has never been fully published. Groß ottenhagen

graves from the discussed period are represented by so-called double layer burial features, with

human cremations on top of horse burials. The burial rites and grave goods at the cemetery are

discussed in the context of archaeological material from the sambian peninsula and southwest

and central lithuania. The relative chronology of Groß ottenhagen is based on an analysis of

grave goods, as well as the stratigraphy and the spatial distribution of the graves. According to

the absence of imported/status goods at Groß ottenhagen, the cemetery probably belonged to a

peripheral group of the late sambian-natangian region culture of the Prussians.
