Chongam-ri Earthen Castle

The Chongam-ri Earthen Castle, located near Pyongyang, North Korea, is a significant archaeological site believed to date back to the Gojoseon period. This crescent-shaped castle, stretching approximately 3450 meters, is constructed of alternating layers of soil, rock, and sand, reflecting the typical earthen fortification techniques of its time. Classified as one of the National Treasures of North Korea, the site offers insights into the defensive strategies and construction methods employed during the early Iron Age. Additionally, the discovery of a jeweled, gilded crown dissolved in mercury, dating from the Three Kingdoms period, highlights the site's continued use and significance well into the early post-classical period. The castle serves as an important link to understanding the evolution of early Korean fortifications and cultural exchanges.
