Cheonggyecheon Stream is a 11-kilometer-long urban stream located in Seoul, South Korea. It flows through the heart of the city, providing a natural oasis amidst the urban landscape. The stream was restored in 2005, transforming a previously covered waterway into a vibrant public space that features walking paths, bridges, and various art installations. The restoration project aimed to improve the environment and enhance the quality of life for residents and visitors. Today, Cheonggyecheon Stream is a popular destination for both locals and tourists, offering a peaceful retreat and a scenic spot for leisure activities, cultural events, and community gatherings.
