Seongdangpogu Village sits on the site of "Seongdangchang," a Joseon-dynasty granary that stored tribute grain collected from local farmers as tax. Government transport ships once sailed all the way here to carry that grain off toward the capital. Nearby, Ungpo's "Gomgae Landing" — literally "bear inlet" — reportedly took its name from the shape of the port, said to resemble a bear drinking from the waters of the Geum River.
This stretch of riverbank thrived through the late Joseon period as commerce and craft industries developed, growing into a bustling river port. But everything changed with the arrival of the railway during the Japanese colonial period. As the movement of goods shifted from waterways to rail lines, the port's function as a river-shipping hub collapsed rapidly, and the landing eventually shut down entirely. It stayed largely forgotten for decades, until 2009, when a public design project run by Korea's Ministry of Culture, Sports and Tourism restored the ecological riverbank, rebuilt the old landing, and added walking trails. Today it's known well enough to be listed among the seven best sunset spots on Korea's west coast. Where boats once carried tax grain up and down the river, people with cameras now wait for the sunset.
