Early medieval island-type lake dwellings in north-western Poland: Western Slavonic crannogs?

In many regions of Europe there are so-called lake-dwellings, which were described in 1890 by Robert Munro, and have a close spatial and functional relation withinland water systems and seas. Settlements of this type are also known from the area of north-western Poland, where the landscape is dominated by lakes. Characteristicamong them are early medieval settlements entirely occupying small islands located within lake basins (Parsęcko, Żółte and Myślibórz in Pomerania – Pomorze; Nowy Dworek, Chycina and Lubniewice in Lubusz Land – ziemia lubuska). In their external appearance, they resemble British crannogs, especially in their size, the anthropogenic structure of the islands, wooden quays, piers and bridge crossings connecting the islands with the nearby mainland. An important feature of the islands where such structures are sited is their characteristic location – directly on the long-distance routes, in the settlement border zone, in the vicinity of the main watersheds of Lubusz Land andPomerania. They were also part of local settlement clusters, which often included contemporary defensive settlements. They were central places, especially important from the point of view of the identity of local territorial communities. Their functions should be considered not only in the social and political dimension, but probably also in the mythical and sacral one.
