Jamsillaru Station is a station on the Seoul Subway Line 2. Its former name literally means "in the fortress," probably referring to the nearby Mongchon and Pungnap earthen walls, and it was also named from Seongnae-cheon. It is also the closest subway station to the Asan Medical Center.
The station was renamed from "Seongnae" in order to avoid confusion with the Songnae station.
