Gasan-dong is a neighborhood located in
Geumcheon District. Originally, it was part of
Garibong-dong. On March 1, 1995, when Geumcheon District was established as a separate administrative district from
Guro District, the area was divided between the two districts. The portion that remained under Guro District retained the name Garibong-dong, while the part that became part of Geumcheon District was renamed Gasan-dong. The name "Gasan-dong" was created by combining characters from two former villages: "Ga" (가, 嘉) from Garibong-ri and "San" (산, 山) from Doksan-ri. These areas, originally part of
Siheung County (Dong-myeon), were incorporated into
Yeongdeungpo District of Seoul on January 1, 1963. Initially placed under the jurisdiction of the Gwanak Branch Office, the merged administrative unit was given the name "Gasan-dong." However, under a jurisdictional reorganization on May 18, 1970, the name "Gasan-dong" was changed to "Garibong-dong," with Garibong-dong and Doksan-dong designated as legal dong (neighborhood units). Further administrative adjustments on October 1, 1975, officially separated Garibong-dong and Doksan-dong into distinct legal and administrative units. When Geumcheon District was established in 1995, the area formerly known as Gasan-dong (from 1963 to 1970) was reinstated under that name, reflecting its historical roots. ==See also==
