The Songsan-ri tomb is considered to be a place where there is a high probability of the existence of facilities related to the tombs built during the Woongjin period of Baekje, due to the existence of the royal tombs of Baekje and surrounding ruins such as the communist castle. However, after the Japanese colonial period, the terrain surrounding Songsan Rigogun was a constant loss of terrain due to deforestation, cultivation of farmland, and construction of buildings. Therefore, by analyzing the topographical approach and the current geographic topographical environment and comparing it with the various data left behind, the location characteristics of Songsan-ri Tumulus Cluster were materialized. Songsan-ri’s burial mound was selected from the viewpoint of Feng Shui geography influenced by Namjo, and it seems that it utilizes several branched terrains centered around Songsan. The location characteristics of Songsan-ri’s burial mounds become clearer as a result of understanding the relationship between the various ruins of the nearby royal roads and Gongju city, especially the estimated Daetongsaji. The arrangement of ridges, scents, and entry spaces as ridges was arranged in accordance with the shape of the terrain. In other words, Songsan Rigobungun selected the current location as a terrain that could encompass both the nearby royal roads and the estimated Daetongsa Temple along with the selection of Feng Shui geographic location, and they are thought to have formed a landscape that is organically connected to each other.
