Cheonggyecheon is an 11 km long modern stream that runs through downtown Seoul. It existed only as a neglected waterway hidden by an overpass until it was restored in 2005. Today, Cheonggyecheon Stream has been transformed into a haven of natural beauty amidst the bustle of city life. The stream was covered with an elevated highway after the Korean War (1950-1953), as part of the country’s post-war economic development. Then in 2003, the elevated highway was removed to restore the stream to its present form today. The stream starts from Cheonggye Plaza, a popular cultural arts venue, and passes under the 22 bridges before flowing into the Hangang (River), with many attractions along its length.
