Gwanggaeto Stele
The stele is one of the major primary sources for the history of Goguryeo, and supplies invaluable historical detail on Gwanggaeto's reign as well as insights into Goguryeo mythology. It has also become a focal point of national rivalries in East Asia manifested in the interpretations of the stele's inscription and the place of Goguryeo in modern historical narratives. An exact replica of the Gwanggaeto Stele stands on the grounds of War Memorial of Seoul and the rubbed copies made in 1881 and 1883 are in the custody of China and Japan.
