The Ljubljana Marshes Wheel is a wooden wheel that was found in the Ljubljana Marshes some south of Ljubljana, the capital of Slovenia, in 2002. Radiocarbon dating, performed in the VERA laboratory (Vienna Environmental Research Accelerator) in Vienna, showed that it is approximately 5,150 years old, which makes it the oldest wooden wheel yet discovered. It was discovered by a team of Slovene archeologists from the Ljubljana Institute of Archaeology, a part of the Research Center at the Slovene Academy of Arts and Sciences, under the guidance of Anton Velušček. ==The archeological site== Remainings of pile dwellings were discovered in the Ljubljana Marshes as early as in 1875. Since 2011, the site has been protected as a UNESCO World Heritage Site as an example of prehistoric pile dwellings around the Alps, a special form of dwellings in areas with lakes and marshes. The archaeologists at the excavation site identified over one thousand piles in the river-bed of the Ig river, near Ig. They reconstructed the dwellings of in size, separated by approximately . The analyses of the piles revealed that the dwellings were repaired each year and that a new house had to be built on the same place in as little as 10 to 20 years. The oldest inhabitants settled in the region as early as 9,000 years ago; in the Middle Stone Age they built temporary residences on isolated rocks in the marsh and on the fringe and they lived by hunting and gathering. The permanent settlements were not built until the first farmers appeared approximately 6,500 years ago in the time of the Late Stone Age.
