This video shows recreations of prehistoric “Pile Dwellings” along lakes in the Alps from the Neolithic period which dates from 5,000 BC - 500 BC.  From the video page: “The UNESCO World Heritage prehistoric pile dwellings (stilt houses) around the Alps, in Germany, Switzerland, France, Austria and Italy was quite a difficult World Heritage site to visit!  Despite there being hundreds of remains scattered around, almost all of them are submerged in several meters of water, which doesn't make for an interesting video.  But join me as I visit the pile dwellings museum in Unteruhldingen, Germany.”
