The Norway unesco card wasn't the only one i got these last days, i've also received this card sent by Janet. The card shows stilt houses at the Pfahlbau Museum Unteruhldingen. This is an archaeological open air museum on Lake Constance (Bodensee) in Uhldingen-Mühlhofen, Germany, consisting of reconstructions of stilt houses or lake dwellings from the Neolithic Stone Age and Bronze Age.

Uhldingen-Mühlhofen is one of the 111 sites classified as Unesco WHS last June, on the list under the name "Prehistoric Pile dwellings around the Alps". This prehistoric stilt house settlements are also located in Austria, France, Italy, Slovenia, and Switzerland.

This serial property of 111 small individual sites encompasses the remains of prehistoric pile-dwelling (or stilt house) settlements in and around the Alps built from around 5000 to 500 B.C. on the edges of lakes, rivers or wetlands. Excavations, only conducted in 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. Fifty-six of the sites are located in Switzerland. 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. - in: www.whc.unesco.org/en/list/1363
