Regional characteristics
Rivers and streams in Seongdong-gu, such as Jungnangcheon Stream and Cheonggyecheon Stream which cover the Wangsimni, Majang, and Yongdap area, have greatly contributed to Seongdong-gu to grow into the center of transportation and commerce. Especially, Yongdap-dong acts as a hub for used vehicles, which take up most of the used vehicles sales in Seoul.
There were many old and worn-down houses in Geumho-dong, Oksu-dong, Haengdang-dong, and Eungbong-dong, among others, but the ongoing redevelopment and reconstruction projects are revamping the areas into a pleasant housing environment that faces the southern banks of the Hangang River.
For transportation, subway lines 2, 3, and 5 and the Bundang Line pass by, making Seongdong-gu the transport hub of northeast Seoul connecting Gangnam-gu and Gangbuk-gu. The Seongsu-dong area, the core of IT complexes, is expected to develop as an IT hub which will lead the regional economy for an abundant future.

The transportation hub connecting Gangnam-gu and Gangbuk-gu centered around Wangsimni
There are 17 subway stations from subway lines 2, 3, and 5, the Gyeongui–Jungang Line, and the Bundang Line in Seongdong-gu. This makes Seongdong-gu the transport hub of northeast Seoul connecting Gangnam-gu and Gangbuk-gu with the Donghodaegyo Bridge and the Seongsudaegyo Bridge.

A district of water that retains Seoul’s longest waterside
As a district of water that borders on a total 14.2 km waterside, including Cheonggyecheon and Jungnangcheon Streams and the Hangang River, Seongdong-gu will continue to flourish through active waterside development.

A multi-dimensional district with manufacturing, logistics, and residential functions
Seongdong-gu offers diverse functions, such as a manufacturing district with the Seongsu heavy-industries area of 2.17 ㎢, a logistical district with the Yongdap-dong used car market and the Majang Livestock Market, and a residential district with large apartment complexes in Geumho-dong, Oksu-dong, and Haengdang-dong.
