Amsa-dong Prehistoric Site
Jeulmun-period Neolithic pit-house settlement on the Han River in Gangdong District, Seoul - the only major Neolithic settlement still visible inside the modern city, with reconstructed umjip pit-houses and an open-air museum. Historic Site of South Korea since 1979. Coordinate cross-checked two ways: Wikipedia infobox (37.56/127.129) against OSM's own node for the site (37.5610/127.1306), about 170m apart. Note: Wikipedia's lead says '3,000 to 4,000 years before the present' while its body dates the umjip to around 4000 BCE; the body matches standard Jeulmun scholarship and is used here.
