Heunginjimun, literally "Gate of Rising Benevolence" or more commonly known as Dongdaemun, is one of The Eight Gates of Seoul in the Fortress Wall of Seoul, a prominent landmark in central Seoul, South Korea. The Korean name "Dongdaemun" means "Great East Gate," and it was so named because it was the major eastern gate in the wall that surrounded Seoul during the Joseon Dynasty. The gate is located at Jongno 6-ga in Jongno-gu.
The structure was first built by King Taejo during his fifth year of reign (1398). It was renovated in 1453, and the current structure is the one rebuilt in 1869.
In August 2011, the roof of the gate was partially damaged by record rainfall. The rain-inflicted damage includes chipped roof's ridge. An official of the Cultural Heritage Administration stated that "The aged gate underwent repairs in 1998 and seems to have become soaked in heavy rains".
Heunginjimun shows architectural style of the late Joseon period. The most unusual characteristic is its built outer wall, Ongseong. Ongseong was constructed to compensate the weakness of the target from multiple invaders. It protects the gate and is a beautiful addition.
