Overview
The Amsa-dong site in Seoul, representing Korea's prehistoric era, is a Neolithic site located along the Han River facing Achasan Fortress. Three cultural layers have been identified, and radiocarbon measurements indicate the site dates back to 4,000~3,000 BC. Multiple excavations have uncovered more than 40 house sites, attached facilities, and stone mounds. The traces of Neolithic people's lives, centered around the Han River, remain intact as they lived as fishermen and gatherers. The house site is dug into a square shape with rounded or cornered floors, measuring about 5~6 meters in length and 70~100 cm in depth. A stone hearth site is also visible in the center of the house site, with the entrance mainly facing south. There are usually four pillar holes, and it appears that the roof was built by erecting pillars at the corners. Additionally, many pottery with pointed comb patterns and pointed bottoms was found, along with stone axes, net weights, and burnt acorns. The Amsa-dong site in Seoul is a representative Neolithic site in the Han River basin and is the largest village-level site identified in Korea to date, making it extremely important. Additionally, many artifacts have been excavated that provide insights into daily life at that time.
