Dongdaemun: The Deep Story of Heunginjimun Entwined with Its Name


This gate, which many people call Dongdaemun, has the official name **Heunginjimun**. It gained the nickname ‘Dongdaemun’ because it is located in the east among the eight gates of the Seoul City Wall, but its name contains the Confucian ideal of ‘promoting benevolence (仁)’. The Seoul City Wall, the old name for Seoul Hanyangdoseong, was a defense system built in the past to protect Hanyangbu, where important national facilities were located. This gate was more than just a passage; it was a symbolic entity in which Joseon’s founding ideology and philosophy were embedded.
