- Cheonggyecheon Stream made its debut in the fall of 2005 and ever since has been an “oasis in the city” beloved by many Seoul citizens. Stretching10.85km long and with a basin area of 59.83㎢, its name during the Joseon Period was “Gaecheon”(開川) and it once played the role of a sewer that kept the capital city clean. Now it is a stream in the heart of the city, and it has been restored based on the historical and cultural data like Gwangtonggyo Bridge and the wall painting of Jeongjo banchado (Royal Procession of King Jeongjo), and the habitat of many plants and animals like day lilies and herons.
