## Geography

Dongdaemun District borders Seongbuk District to the north-west, Jungnang District to the east (with the Jungnangcheon stream forming the border), Gwangjin District to the south-east, Seongdong District to the south, meets Jung District at a point in the south-west and borders Jongno District to the west. The busiest neighborhood of the district is the Cheongnyangni area - a large commercial zone formed around Cheongnyangni Station, one of the secondary CBDs of Seoul. Dongdaemun District is named after the east gate in Seoul's city walls, Dongdaemun, but Dongdaemun itself is actually located in Jongno District. This is due to an administrative border change.
