Dongsam-dong Shell Midden or Shell Mound Museum (Hanja: 東三洞貝塚展示館) is located on the west coast of Yeongdo Island in Dongsam-dong, Yeongdo-gu, Busan Metropole, the Republic of Korea.
This archaeological site consists of a midden of shells of various mollusk taxa that were discarded in a relatively small or restricted area by people who lived there in the Jeulmun Pottery Period. It was excavated three times by archaeologists of the National Museum of Korea from 1969 and was found to be the among oldest Jeulmun middens so far discovered in the southern part of the Korean peninsula. The presence of Yunggimun (appliqué-pattern) pottery indicates the site was occupied for a time between 8000-7000 BC, but many absolute dates generated from carbon that was excavated from the site indicate the site was also occupied in the Middle (c. 3500 BC) and Late (c. 2000 BC) Jeulmun sub-periods.
A variety of artifacts, including three types of pottery (patternless, comb-patterned, and appliqué patterned), and tools made of bone and stone were uncovered. Artifacts and features from Dongsam-dong provide insight into the way the people of the area lived as well as into the cultural trends of the times.
The excavated remains have also proved to be valuable for estimating both the influences of Siberian culture on Korea and prehistoric exchange between southern Korea and Kyūshū, Japan.
Many kinds of fish, shells and animal bones as well as Comb-pattern Pottery, bones, and earthenware have been discovered at Dongsam-dong Shell Midden. Recently, Busan Museum research found not only foxtail millet - millet which was a common grain in Korean peninsula - but also Jomon pottery obsidian flakes that shows the vestige of culture exchange during the Neolithic period between Korea and Japan.
Therefore it is a very important relic to enable us to prove the character and essence of the Korea culture during the Neolithic period. The Busan Museum opened the typical cultural inheritances of the Neolithic period, Dongsam-dong Shell Midden sites and remains to public and opened Dongsam Shell-heap Exhibition on April 24, 2002 in a view to using it as a historic site after the Memorial Hall for Provisional Capital and Bokcheon Museum were open. Though this is a small Exhibition Hall, we will continue to put our efforts to discover History and Culture of the Neolithic period through Dongsam-dong Shell Midden Exhibition Hall.
