The Polish Pyramids or Kuyavian Pyramids are a group of megalithic tombs that have been discovered in Wietrzychowice, Poland. Built in 4000 years BC, Polish Pyramids probably belong to the Funnelbeaker culture community, which lived on the land from the 5th to the 3rd millennium BC. They were shaped like an elongated triangle and surrounded with large stone blocks. Their base was 6 to 15 meters wide and up to 150 meters long. The structures were up to 3 meters high and as a rule, single elite burials were found under the embankments.
