Railroad construction through a farm on the Danish island of Falster has revealed a 5,000-year-old Neolithic site hiding an advanced technology—a stone paved root cellar.

Archaeology researchers from the Museum Lolland-Falster, along with Aarhus University, Denmark, have analyzed the site in a paper, "Stone-Paved Cellars in the Stone Age? Archaeological Evidence for a Neolithic Subterranean Construction from Nygårdsvej 3, Falster, Denmark," published online in the journal Radiocarbon.

The emergence of the Funnel Beaker Culture around 6,000 years ago brought the Scandinavian region's first switch to agriculture and domesticated animals (sheep, goats, cattle), leading to a more sedentary lifestyle. With the new way of life came the region's first construction of houses, megalithic tombs (dolmens), and landscape-altering structures, a huge shift away from the highly mobile hunter–gatherer strategy of the Late Mesolithic.

Excavations at the site, Nygårdsvej 3, uncovered two phases of house construction. Both structures were built using a common Funnel Beaker Culture design (the Mossby-type), where interior posts provide support for a large double-span roof. Phase one included 38 post holes, while phase two had 35, indicating that a significant amount of architectural planning was involved.
