At the southern edge of Greenland lies Kujataa, an area of sub-arctic farming that is the first known instance of agriculture in the Arctic. This area is also the oldest evidence showing the spread of the Old Norse culture beyond Europe. From the 10th to 15th centuries, as well as from the 18th century to the present, the unique combination of farming and hunting for marine mammals has been practiced in this region. This activity was the reason for Kujataa's inscription on the UNESCO World Heritage List in 2017. Kujataa's boundaries extend from Nunap Isua in the south to Nunarsuit Island, a distance of about 250 kilometers to the north. The World Heritage Site encloses 5 components, all within the same region.
