Excavations, conducted in only some of the sites, have yielded evidence that provides insight into life in prehistoric times during the Neolithic and Bronze Age in Alpine Europe, and the way communities interacted with their environment. As the nomination stated, the settlements are a unique group of exceptionally well-preserved and culturally rich archaeological sites which constitute one of the most important sources for the study of early agrarian societies in the region.

Contrary to popular belief, the houses were not erected over water, but on nearby marshy land. They were set on piles to protect against occasional flooding.
