Mausoleum of Tangun

The Mausoleum of Tangun is an ancient burial site in Kangdong near Pyongyang, North Korea [1]. It is claimed by North Korea to be the tomb of Tangun, founder of Gojoseon, the first Korean kingdom [1]. A pyramid was built on top of the grave in 1994, consisting of 1994 blocks of stone [1]. The complex occupies about 1.8 km² on the slope of Mount Taebak [1]. A nail found in the mausoleum, dating to the Goguryeo period, has been the subject of much controversy [1]. This discovery has thus led some North Korean historians to conclude that the mausoleum was discovered and renovated during that period [1]. South Korean historians think it's more likely to be a tomb of a regional power during the Goguryeo kingdom based on the artifacts found at the site [1].
