The pile dwelling settlement in Kehrsiten was designated a UNESCO World Heritage Site on 27 June 2011, together with other pile dwelling settlements in the Alpine region.
In June 2003, sport divers discovered the remains of a Neolithic pile-dwelling settlement from the 4th millennium BC in Lake Lucerne. This is the oldest evidence of humans in Nidwalden.
The pile-dwelling settlements of the Alpine region are among the most important archaeological cultural assets in Europe. The sites offer exceptional preservation conditions for organic materials such as wood, textiles, plant remains or bones, which are excellently preserved in the mud under exclusion of air. They therefore allow unique insights into the early peasant cultures of Central Europe.
