Ilsan
Ilsan New Town refers to a planned city surrounding Ilsandong-gu and Ilsanseo-gu of Goyang.
Ilsan is located northwest of Seoul. Like other satellite cities in the Seoul National Capital Area such as Bundang, Ilsan was planned in order to alleviate housing shortages in the city of Seoul. Ilsan has experienced phenomenal growth in the past 15 years, usually drawing in younger generations of upper middle-class and upper-class Koreans.
