The name of the station, "Wangsimni," is related to a historical account dating from 14th century Korea. After establishing and becoming the first king of the Joseon dynasty, Yi Seong-gye presented the great Buddhist monk Muhak with the task of finding a site for the new capital. After searching for a suitable place, the monk stopped and saw an old farmer passing by on his ox. The farmer pointed toward the northwest and said to him, wangsimni (往十里), literally meaning 'go ten more li (li = a unit measure that equals to one-third of a mile).' The startled Muhak went to the northwest as he was told and ended up at the southern foot of Mt. Bugak, where Gyeongbokgung now stands. This was how Hanyang (present-day Seoul) was born.
