Igeum-dong is a complex archaeological site located in Igeum-dong, Samcheonpo in Sacheon-si, South Gyeongsang Province, South Korea. This prehistoric archaeological site is important in Korean prehistory because it represents solid evidence that simple chiefdoms formed in as early as the Middle Mumun, some 950 years before the first state-level societies formed in Korea. The settlement is dated by pottery, pit-house types, and an AMS radiocarbon date to the Late Middle Mumun Pottery Period (c. 700–550 BC). Test excavations were conducted in 1997, and wide-scope horizontal excavations took place in 1998 and 1999.
The site contains a megalithic cemetery with 63 burials, some of them with artifacts of high-status, 25 raised-floor buildings, including the two largest raised-floor buildings in Korean prehistory, 5 ditches, 1 palisade, and 27 pit-houses. The intra-site patterns show that the site is divided up into at least three ‘zones’: 1) mortuary, (2) feasting-meeting, and (3) residential.
