Mapo-gu's historical roots can be traced back to the early Joseon Dynasty when the area fell under the jurisdiction of Hanseongbu, the capital administration. Though it lay within a short distance—about 10 li—from the city walls, it had not yet been formed into an independent administrative district. Later in the Joseon period, Hanseongbu expanded to include five new administrative regions: Dumobang, Hangangbang, Dunjibang, Yongsanbang, and Seogangbang. Parts of present-day Mapo-gu became included within the boundaries of Yongsanbang and Seogangbang. During the Joseon period, Mapo held geographical and economic significance due to its location along the Han River. It served as a key river port and ferry crossing, situated near Ha-joongdo (modern-day Yeouido), linking to inland routes that led to places such as
Siheung. Mapo was one of the "Five Ports of the Han River" (오강, 五江), alongside Ttukseom, Noryang, Yongsan, and Yanghwajin. These ports were central to unloading, storing, and redistributing goods that traveled via the Han River, which served as a vital transportation route through
central Korea. Mapo, along with
Yongsan and Yanghwajin, handled large quantities of grain from the southern provinces, as well as seafood like shrimp and croaker brought in from the
Yellow Sea, making it a key hub in the redistribution of
agricultural and
marine products. A major administrative shift occurred in 1910 under
Japanese colonial rule. Hanseongbu was renamed Gyeongseongbu and placed under
Gyeonggi-do's authority. The following year, it was granted official administrative status through Gyeonggi-do's ordinance. During this reorganization, Yongsanbang and Seogangbang were reclassified as Yongsan-myeon and Seogang-myeon, each overseeing numerous small districts. In 1913, another reorganization placed much of what we now consider Mapo-gu into the western portion of Gyeongseong-bu, while Seogang-myeon was incorporated into Goyang-gun, also within Gyeonggi Province. Over the next decades, administrative boundaries were adjusted several times. A significant development came on October 23, 1944, when parts of
Seodaemun-gu and
Yongsan-gu were separated to formally establish Mapo-gu as an independent district. At the time of its founding, Mapo-gu comprised 23 towns, including names like Gongdeok-jeong, Ahyeon-jeong, Hapjeong-jeong, and Mangwon-jeong. Following Korea's liberation from Japanese rule in 1945 and the arrival of the
U.S. military government, various administrative terms were updated—for instance, "jeong" became "dong," and district offices adopted new titles. By 1955, further restructuring took place, streamlining the smaller districts into 19 administrative dongs such as
Ahyeon 1-dong through 5-dong,
Daeheung-dong,
Singongdeok-dong, and others. Later adjustments in the 1980s, including those made in 1985 and 1989, redefined some neighborhood boundaries—for example, parts of
Yonggang-dong were folded into
Yeomri-dong, and segments of
Mangwon-dong were reassigned to nearby
Seogyo-dong and
Hapjeong-dong. ==Mapo District Office==
