A Study on the Constructionand Social Meaning of ‘mound-shaped monument’ in the Yeongsangang River Basin

his study starts with the problem consciousness that it is difficult to define the concept of tombs in the Yeongsangang River basin as ancient tombs with data such as Sumyo(壽墓) or Heomyo(虛墓). Since there is no central burial facility, it is difficult to see it as an ancient tomb, and it is judged as a ‘mound-shaped monument’ in terms of shape and function. As a result of the mound-shaped monument review, it can be found in seven places from the upstream station of the Yeongsangang River to the downstream station. The shape and structure are the same as the 'mound' of the ancient tomb, and can be discussed in five ways: location, number, stone cover status, shape, and ditch facilities. The characteristics are that there are many places with a good view, many square shapes, many made of one, and many without ditch facilities. It can be said that the concept was different from the tombs gathered on the flat land with ditches. It is a ‘signature symbol’ role that shows the status of the group, and it seems to be a trend phenomenon that creates a huge ancient tomb in that it matches its appearance and function within a certain period of time. The Yeongsangang River basin was created from the middle of the 5th century to diversify its social meaning and pray for authority and well-being. From the existence of the 'mound-shaped monument' it can be seen that even in the process of gradually transitioning from Mahan to Baekje, it was completed as a tomb landscape with various components in addition to the mound. In the future, extensive archaeological approaches to space composition are expected to be made to deepen consciousness research such as Mahan's grave and funeral.
