Cheonggyecheon
During the Japanese colonial period, it came to get called "Cheonggye" as it is called today, supposedly from 1914, when the colonialists rearranged stream names in Korea. In this perion, the large-scale dredging of this stream was planned in terms of a modern urban planning by Japan but it wasn't carried out because of lack of funds. Therefore, the urban improvement project was neglected.
