The settlement at Biskupin belongs to the Hallstatt C and D periods (early Iron Age, 800-650 BC and 650-475 BC). However, dendrochronological analysis provided more accurate dating. It proved that oak wood used in the construction of the settlement was cut down between 747-722 B.C. Over half of the wood used was cut during the winter of 738/737 B.C.
What is very interesting is that the tradition of building dwellings and fortifications from logs was during the early Iron age found only in Pomeranian culture south of Baltic sea and not in Jutland or in Scandinavia.
The tradition of building log cabins was continued by the Central European Celts. This is a reconstruction of a Celtic house in Havranok, Slovakia.
