On August 13, 1949, Goyang-gun's Ttukdo-myeon (an administrative district) was incorporated into Seoul, leading to the establishment of the Ttukdo Branch Office in the newly formed city.

This was followed by further restructuring, such as the dissolution of the Ttukdo Branch Office in 1964, with its jurisdiction being incorporated directly into the newly-formed Seongdong District.

The same year, Gwangjin District was formally incorporated as an administrative subdivision of the Seoul Special Metropolitan City.

Most of the remaining area is residential, but consist not of apartment buildings characteristic of the city, but of three or four-story row houses separated by small roads and alleyways.

On the left of the station is Dong Seoul Bus Terminal, where buses serve various destinations including Busan, Gwangju, Daegu, and Daejeon.

Due to the geographical landscape of the district, which borders Mountain Acha (Achasan) and the Han River, the territory of Gwangjin was used as an arena for Goguryeo, Baekje, and Silla to compete with each other.

Apart from strategic purposes, Achasan is also the setting of a legendary love story which revolves around General Ondal, the son-in-law of King Pyeongwon of Goguryeo, and Princess Pyeonggang.

During the Joseon period, many nobles and scholars settled in the area, reciting lyrical poems and writing books.

(Seongdong-gu) ← Konkuk University — Guui — Gangbyeon → (Songpa-gu) Seoul Subway Line 5 runs through Gwangjin District with stops at Gunja, Achasan, and Gwangnaru stations.
