Cheonggyecheon, a 10-kilometer-long stream in the heart of Seoul, was restored between 2003 and 2005 after the demolition of an old elevated highway. The restoration transformed it into a vibrant green space and a sanctuary for city dwellers.
Cheonggyecheon is now home to clear waters, lush vegetation and a variety of wildlife. A Seoul City survey reported that as of 2022, 492 plant species, 41 bird species and 21 fish species inhabit the area.
