 Songguk-ri is a main point of reference in Korean prehistory—Korean archaeologists have represented the prehistoric village and the material culture excavated from there as the type-site for Middle Mumun Culture in southern Korea.Excavations began there in 1975 and Songguk-ri was one of the first archaeological sites in South Korea to yield bronze artifacts, large tubular greenstone beads, and pit-houses with rounded plan-shapes.Rounded pit-houses similar with those of Songguk-ri were later found at other archaeological sites along with a suite of other co-occurring artifacts prompting archaeologists to use Songguk-ri as the type site for Middle Mumun culture and label features and artifacts from there and other Middle Mumun sites as 'Songguk-ri Style'.
