Established in 1907 as a salt farm for solar salt production, the Juan Salt Farm in Incheon holds the historical title of Korea's first salt farm. Despite its closure in the 1960s and subsequent conversion to the Juan National Industrial Complex, part of the Gyeongin Industrial Complex, the site left no significant traces. However, a marker was erected in 1989 in Sipjeong-dong, Bupyeong-gu, Incheon, marking the site of Korea's first solar salt production. While research and investigation into the Juan Salt Farm have continued, the area's administrative division has left the marker unmanaged and neglected. The marker is located somewhat off-site from the experimental salt farm, the first salt production site among the eight districts of the Juan Salt Farm, and the marker's content needs further revision. The Juan Salt Farm is a key point in Incheon's transformation during the Japanese colonial period and the industrialization period. The Juan Salt Farm Marker is seen as an important means of linking the present with the history of the place, and a plan for its utilization was proposed.
