There are seven tombs grouped together in Neungsan-li, which is located on the way to Nonsan from Buyeo. Thought to have been the tombs of kings or royal family members from the Baekje Kingdom, they are smaller in scale than the Shilla tombs found in Gyeongju. One central tomb is similar in structure to King Muryeong's grave in Songsan-li. Most of the artifacts excavated from the tombs are now in the collection of the Buyeo National Museum.
