A ribbon of water sparkles before you. This is Cheonggyecheon. Its story begins long ago a natural stream flowing through Seoul. It was called Gaecheon. Kings of the Joseon Dynasty maintained it. They dredged it. They built bridges. They even considered it a national project.
But times changed. After the Korean War the stream became neglected. It filled with trash. Shabby houses lined its banks. The concrete jungle swallowed it whole. In its place rose the Cheonggye Expressway. A symbol of Korea’s rapid economic growth but a scar on Seoul’s heart.
Then Mayor Lee Myung-bak had a vision. A bold vision. He decided to remove the expressway. To restore Cheonggyecheon. It wasn’t easy. There was opposition. Concerns about traffic. Doubts about the cost. Over 386 billion won. About 281 million US dollars. A massive undertaking.
But the project went ahead. The expressway came down. The stream reappeared. Not just a stream but a revitalized urban space. Twenty-two bridges now span Cheonggyecheon. Some historic bridges were carefully restored. This was a balancing act. History and modernity.
The restoration didn’t just bring back a stream. It brought back life. Biodiversity soared. Plants insects birds fish all thrived. The number of plant species increased from 62 to 308. The number of fish species from 4 to 25. An astonishing 639% increase in biodiversity. The city cooled down. The urban heat island effect diminished. Air quality improved. Respiratory illnesses decreased. Even traffic flow improved. A real-life example of Braess’s paradox.
Today Cheonggyecheon is a beloved space. Residents and tourists stroll along its banks. They enjoy the fountains. The waterfalls. The bridges. The restored ecosystem. They reflect on the stream’s journey from neglected eyesore to vibrant heart of the city. A testament to human resilience. A symbol of renewal and harmony.
Cheonggyecheon is a reminder. A reminder that even in the midst of concrete and progress. Nature’s beauty and power can be revived. It’s a place to pause. To reflect. To appreciate the beauty of Seoul’s unexpected oasis.
