Dolmen Tombs

Megalithic dolmens appear in Korean peninsula and Manchuria around 2000 BCE to 400 BCE. Around 900 BCE, burial practices become more elaborate, a reflection of increasing social stratification. Goindol, the dolmen tombs in Korea and Manchuria, comprising upright stones supporting a horizontal slab, are more numerous in Korea than in other parts of East Asia. Other new forms of burial are stone cists (underground burial chambers lined with stone) and earthenware jar coffins. The bronze objects, pottery, and jade ornaments recovered from dolmens and stone cists indicate that such tombs were reserved for the elite class.

Around the 6th century BCE, burnished red wares, made of a fine iron-rich clay and characterized by a smooth, lustrous surface, appear in dolmen tombs, as well as in domestic bowls and cups.
