Illustrations of history

Wikipedia has a very detailed article on them: https://en.wikipedia.org/wiki/Cucuteni%E2%80%93Trypillia_culture

One of the most notable aspects of this culture was the periodic destruction of settlements, with each single-habitation site having a lifetime of roughly 60 to 80 years. The purpose of burning these settlements is a subject of debate among scholars; some of the settlements were reconstructed several times on top of earlier habitational levels, preserving the shape and the orientation of the older buildings. One location, the Poduri site in Romania, revealed thirteen habitation levels that were constructed on top of each other over many years.
