The Non-stylobate The Stone-Mound Tomb in South Korea is widely distributed in the Imjin River basin, the Bukhan River basin, the Namhan River basin, the downstream of the Han River. These stone tombs are basically characterized by a single or several burial chambers placed in a single stone mound. In the case of group tombs, it was created by adding a new tombstone using one wall of the existing tombstone. It is distinct from Goguryeo's Jeokseokchong that there are several burial bodies in one.
The origin of the stone tombs in the South Korean region has not yet been clearly identified, and comparative research with data from the North Korean region is necessary.
However, at present, it is known that the tradition appeared in the Imjin River basin starting in the 3rd century and gradually spread to the Bukhangang River basin, the lower reaches of the Han River, and the Namhangang River basin through artifacts excavated from the stone tombs and nearby settlement sites in each basin, and in the case of the Jeongseon Auraji stone tombs, it has been confirmed that the tradition continued until the 6th century.
There have been various discussions about the construction group of Non-stylobate The Stone-Mound Tombs, including Goguryeo, Baekje, Yae, and Mahan, It is not easy to pinpoint a specific race or group. However, despite the influx of the central culture of Baekje and Silla during the construction of The Non-stylobate The Stone-Mound Tomb, the tradition of The Non-stylobate The Stone-Mound Tomb is maintained, Unlike Baekje and Silla, it can be assumed that it is a “local force” in the culture of Yae(濊), where stones were traditionally used in tombs.
