During the
Joseon period, the neighborhood had different names (Jeongja-dong, Yeom-dong, Gung-dong, Eumwol-ri). Under the Japanese occupation, it was sent to
Gyeonggi Province, and returned to Gyeongseong-bu (Seoul) as Yeonhui-jeong (延禧町). In 1946 it became Yeonhui-dong. Note that the Southern ('nam') part of Yeonhui-dong that joined
Mapo District in 1975 – the section on the other side of the Southern section of the Gyeongui Line – was logically named
Yeonnam-dong. The name is a tribute to the Yeonhuigung palace praised by early Joseon kings, most notably
King Sejong, who often stayed there on week-ends, and had the first Korean silk made in that palace. ==An international educational and residential area==
