The early Bronze Age in Poland began around 2400 BC, while the Iron Age commenced in approximately 750 BC. During this time, the Lusatian culture, spanning both the Bronze and Iron Ages, became particularly prominent. The most famous archaeological find from the prehistory and protohistory of Poland is the Biskupin fortified settlement (now reconstructed as an open-air museum), dating from the Lusatian culture of the late Bronze Age, around 748 BC.
