Biskupin is an archaeological site and a life-size model of an Iron Age fortified settlement (gród) in Poland, Kuyavian-Pomeranian Voivodship. It belongs to the Biskupin group of the Lusatian culture. The excavation and the reconstruction of the prehistoric settlement have played an important part in Polish historical consciousness.
The Museum is situated on a marshy peninsula in the Lake Biskupin, ca. 90 km northeast of Poznań, 8 km south of the small town of Żnin. It is part of the state archaeological museum in Warsaw.
In 1936, the first lifesize model (open air museum) was built on the peninsula, inspired by the Unteruhldingen-pile dwellings in Germany. After the war, the ramparts and one street with houses on both sides were added.
In the 2000's, a film prop "medieval" timber castle has been constructed on a part of the original site.
