The open ritual area is one type of pagan cult site. In this article are presented the results of an analysis of wooden pole frames and constructions from six open ritual areas in the northern Sambian peninsula. Their chronogical time covers the third to the 13th centuries AD. Open ritual areas coexisted with fireplaces and pits. In the early phase pole constructions are characterised by a rectangular shape, and subsequently a roundish shape. Analogies with open ritual areas are known in Poland, Denmark and Germany.
