"The Hangang River flows through the capital city of Seoul, starting from three smaller streams in the central areas of Gangwon-do, Chungcheongbuk-do, and Gyeonggi-do. The river has witnessed the history of the Korean people for over five thousand years, through good and bad times. The riverside parks offer a nice retreat for the citizens of Seoul."
