This is an ancient tomb complex from around the Silla Unification War period located in Chodang-dong, Gangneung.

Scattered across the Chodang-dong beach area, these relics were first urgent-surveyed in 1969. Through numerous excavations, it has been confirmed as a complex site where residential areas and tombs from the Neolithic, Bronze, Iron, and Three Kingdoms periods coexist.

Designated as a National Heritage in 2007, this site covers 59,290㎡. Various artifacts such as gilt-bronze butterfly-shaped ornaments, silver belt decorations, and iron swords have been excavated from Silla-era stone-lined tombs. These findings prove the existence of powerful local forces and the geopolitical importance of the Gangneung region during the Three Kingdoms period. While fences protect the site, visitors can see where artifacts were found, covered by large stones. A nearby park allows for a relaxed visit. After exploring the history, trying Chodang's famous soft tofu is highly recommended.
