The Niedanowo cemetery was discovered in 1937, but systematic archaeological works took place in the years 1959–1970. The burial site in Niedanów was used for long time, from the early Iron Age to the early phase of the Migration Period. The oldest are the Western Baltic barrow culture graves from the early Iron Age, fromca. 100 BC until Mid–2nd century AD. Then it was a graveyard of the Przeworsk culture people, and in the second half of the 2nd century AD it was used by a group of people from the Wielbark culture,until the first half of the 5th century AD. The most ineresting are Przeworsk culture graves, espacially those with stone structures - pavements and wreaths and the Wielbark culture graves, often with stone stelae.
