Lake Seokchon was originally part of the Han River, but after a land reclamation project in 1971, an artificial island was formed by the gradual accumulation of silt from the source, and this formed a separate lake away from the Han River. The new lake now contains two parts; East Lake and West Lake, Songpa Naru Park includes West Lake and Magic Island; It is a man-made island, and the park contains a number of amenities, including small gardens, walking paths, restaurants and cafes, and is considered one of the many popular cultural areas in Seoul.
