Today, the center of Gyeongju is occupied by a cluster of huge tombs resembling hills. They belong to the monarchs and royal family members of Silla between the late 4th century and the 6th century. Most Silla-era artifacts of various golden ornaments that represent the kingdom’s culture, such as crowns, belts, earrings, and rings, originated from this location. The royal tomb complex consists of Cheonmachong (Heavenly Horse Tomb) excavated in 1973 and Hwangnam Daechong (Great Tomb of Hwangnam) excavated from 1973 to 1975, as well as nearby tombs in Hwangnam-dong, Gyeongju.
