Cheonggyecheon is a stream that runs across the city centre of Seoul to the Hangang River. It was once a dusty and heavily polluted area with many traffic and highways. The Koreans restored this stream in 2005 and made it to become a major city retreat and tourist spot. Wonderful place to visit in Seoul. http://english.seoul.go.kr/cheonggye/
As I did not bring my tripod with me, all the evening captures are hand held, very difficult indeed.
