NRICH performed GPR (Ground Penetrating Radar) archeological surveys over the ancient royal tombs in Neungsan-ri, Buyeo County, Chungcheongnam-do Province, a UNESCO World Heritage Site and ROK Historic Site No. 14. Through the survey, it has confirmed the arrangement and sizes of tombs, which were created while Sabi was the capital of the kingdom of Baekje from 538 until its fall in 660 CE.
As the first phase of the long and mid-term scientific investigations of the Neungsan-ri tombs, GPR surveys were carried out over the central part of and entry to the graveyard from 2014 to 2020. The results confirm the traces of circular anomalies that surround each burial mound at some distance. It is believed that the perimeters of the tombs were much larger than the current 20m or so to which they have been restored. NRICH intends to build upon these findings and perform further surveys of the Neungsan-ri tombs to identify the features of the royal tombs from the later Baekje period and discover the ancient kingdom’s system of royal tombs and graves.
