The History

The Cheonggyecheon Stream was originally a naturally flowing river with water falling from Inwangsan Mountain. It was simultaneously a local resource and a hazard for the local residents as it overflowed in monsoon seasons and caused flooding.

Throughout the Joseon Dynasty, the riverside was updated and reconstructed to allow for easier use. The river was nice enough up until the Japanese occupation from 1910 to 1945 at which point it became dirty and polluted.

By 1953, after the Korean War, more people were moving to the city and throwing trash into the dirty water making it even worse. And finally, in 1958, construction began to completely cover the river with an elevated motorway. The Cheonggyecheon Stream was effectively covered and hidden from sight for the next 25 years.

Then in 2003, the mayor, Lee Myung Bak, started a project to remove the highway and restore the stream. The effects of which weren’t fully known until construction was finally completely. As the road was dismantled and nature was brought back to downtown Seoul and 120,000 tonnes of water was pumped in, the restoration project led to numerous benefits for locals and the city of Seoul.

Benefits Of Restoring The Cheonggyecheon Stream

Dismantling the 10 lane highway that carried 170,000 vehicles daily through downtown Seoul encouraged a huge transformation of the downtown area.

• It encouraged transit use. As people couldn’t drive their vehicles as easily through the center of the city, more people were encoraged to take buses or subways. There was actually a 15.1% increase in bus ridership and 3.3% increase in subway ridership between 2003 and 2008.*
• The decrease in vehicles downtown in turn improved the air quality and water quality. There was a 10.3% decrease in air pollution from vehicles.*
• The decrease in pollution also led to a decrease in the temperature downtown. The urban heat island effect was decreased by 4.5%.*
• The better air and water quality and reduction in temperature was an invitation to wildlife to return and today, visitors can see fish, cranes, and other birds happily enjoying the Cheonggyecheon Stream.
• Today, the Cheonggyecheon Stream has more then 64,000 visitors daily as they’re either walking or taking a break from work or enjoying the scenery creating more quality of life opportunities.*

*The stats here were found in the Global Designing Cities Initiative Case Study on the Cheonggyecheon Stream.

Events Held At The Cheonggyecheon Stream

Numerous events are held along the Cheonggyecheon Stream which is why locals and tourists alike flock to the area year round. Generally, the events and installations are held at the beginning of the stream at Gwanghwamun Square and stretch for a few blocks.

In the spring, there are usually art festivals. Though because of Covid, the past couple of years have held the Buddhist lanterns usually seen in the massive Lotus Lantern Festival Parade which unfortunately couldn’t be held.

In the autumn there is the popular Seoul Lantern Festival usually held in October. Lights are strung across the top of the walkway and lanterns are placed in the waterway to enjoy in the evenings.

In the winter, there are still more lanterns placed in the waterway to celebrate the holidays.

No matter the time of the year or the time of the day, you will probably find something fun happening along the Cheonggyecheon Stream in downtown Seoul.

What To See Along The River

Want to walk along the entire Cheonggyecheon Stream like us? Or just want to know what to see along the way? Let’s go step by step starting from the beginning at Gwanghwamun Square all the way out to the Han River.

How long is the Cheonggyecheon Stream?

The Cheonggyecheon Stream is 10.92km long. It starts in downtown Seoul, meets the Jungnangcheon Stream and then empties into the Han River. Are you ready to go for a walk?

Address Notes: The addresses below are the street level addresses as the river stops themselves don’t really have addresses. This should make it easier if you want to head to a certain section but just know as the GPS will say you’ve arrived when you’re street level and you may not be able to see anything, like the art beneath the bridges, until you head down to the riverside level.

“Spring” Sculpture

When you’re walking on the main road and aren’t sure where the Cheonggyecheon Stream starts, just look for the sculpture by Claes Oldenburg and Coosje van Bruggen called “Spring”. The sculpture, created by the Swedish pop artists, is a 20 meter high spiral cone painted in red and blue and is meant to be a symbol of renewal in nature. There was some controversy when it was chosen back in 2006 but has been there since installation and has become a mainstay of the downtown art scene.

• Address: 1 Cheonggyecheon-ro, Jongno-gu, Seoul (서울 종로구 청계천로 1)

---

Waterfall & Rainbows

The entrance to the Cheonggyecheon Stream has a waterfall that pumps water into the stream and the first bridge features some fun rainbow lights. This is often the busiest area as the entrance is here and events start from here. Take a seat along the stream and just enjoy the lights or keep walking on to the next section. This is a beautiful from day into night. Just check out those rainbows, it’s one of the prettiest spots in Seoul at night to take a walk.

• Address: 1 Cheonggyecheon-ro, Jongno-gu, Seoul (서울 종로구 청계천로 1)

Pro Tip: If you want to take a break here, head up to the main street and find HiKR Ground. Opened by the Korea Tourism Organization, it’s an immersive tourism space with multiple floors, a cafe on the top floor, and it’s completely free to enter. It’s a great space to cool off in the summer or warm up in the winter and have some fun while you’re at it.

King Jeongjo’s Royal Procession Mosaic

Just before the Jangtonggyo Bridge, a beautiful tiled mosaic depicting King Jeongjo’s Royal procession begins on the north side of the stream. The mosaic is 192 meters long and is apparently the largest tile wall painting in the world. It is made up of 5,120 individual ceramic tiles. It depicts King Jeongjo leading a royal procession to the tomb of his father in Hwaseong in 1785 escorted by his mother Hyegyeonggung Hong.

You can also see this woodblock map of the streets of Seoul that was produced by Kim Jeongho in 1825. Called Suseon Jeondo, you can recognize numerous names across Seoul that still exist today. The Suseon Jeondo is considered the most outstanding woodblock map of Seoul ever produced during the Joseon Dynasty in terms of accuracy and size.

• Address: 61 Cheonggyecheon-ro, Jongno-gu, Seoul (서울 종로구 청계천로 61) (Starts around here)

Sewoon Bridge (세우교)

Now, this is one of the newest bridges over the stream. The street level bridge has been there for awhile, but there has been a lot of development in the Sewoon Sangga Market area over the past few years and they’ve built a second floor pedestrian bridge from that market to the market on the other side of the stream. Apparently, this used to exist some time ago and now as they redevelop the area, they replaced it. If you want to stop off, head up to Sewoon Sangga for an awesome view of Jongmyo Shrine and Namsan Tower from the rooftop.

• Address: 159 Cheonggyecheon-ro, Jongno-gu, Seoul (서울 종로구 청계천로 159)

Gwangjang Market (광장시장)

While the Gwangjang Market isn’t ON the Cheonggyecheon Stream, if you’re walking along the entire stream like we were, this is where I’d recommend stopping for lunch. Head up to the main road at Baeogae Road and into the market on the north side of the stream. The market runs the entire stretch from that road to Majeon Bridge and there’s not much to see in that section of the Cheonggyecheon Stream so it’s a win/win.

• Address: 88 Changgyeonggung-ro, Jongno-gu, Seoul (서울 종로구 창경궁로 88)

---

Dongdaemun (동대문)

There isn’t much on the stream itself from Gwangjang Market to Dongdaemun. If you’re looking for a generally quieter section, this would be a good section to visit. There are fish and the plants take over a bit more of the path. After Dongdaemun, there are again art installations to check out as you meander. The stream begins to widen a bit after this point and become much more natural and taken over by the plant life.

• Address: 295 Cheonggyecheon-ro, Dongdaemun-gu, Seoul (서울 동대문구 청계천로 295)

Seongbukcheon (선북천)/Cheonggyecheon (청계천) Meeting Point

An interesting aspect of this portion of the river are the giant concrete support pillars which once held the overpass. While the rest of the pillars have been demolished, these ones were left as a monument to that industrial period in Korea’s past and have even been designated as Seoul Future Heritage #248. It’s here that you can really feel how high and big the highway that went through the city once was.

• Address: 443 Cheonggyecheon-ro, Dongdaemun-gu, Seoul (서울 동대문구 청계천로 443)

Cheonggyecheon Ramshackle Houses

Cheonggyecheon Museum (청계천박물관)

Learn about the history and the stream over time at this museum which has a façade in the shape of the stream itself. This is a great opportunity if you have children to let them learn a bit more about the riverside and Korean history. Or if you’re interested in more ecological and historical information on the stream, head in yourself.

• Address: 530 Cheonggyecheon-ro, Seongdong-gu, Seoul (서울 성동구 청계천로 530)
• Hours: Tuesday – Friday: 9:00am ~ 7:00pm; Weekends: 9:00am ~ 6:00pm in the winter / 9:00am ~ 7:00pm in the summer
• Admission: FREE

Museum Onward

From the Cheonggyecheon Museum onward, the path is a bit more overgrown with more natural space alongside the paths and then it hits the Jungnangcheon Stream (중랑천) which filters south to the Han River. This is where a lot more bicyclists are on the path as well as they don’t usually hit up the beginning of the Cheonggyecheon where there are much more pedestrians in the way.

If you make it all the way out to the Han River, you’ll come out near Eungbongsan on the western side or Seoul Forest in Seongsu-dong on the eastern side.

The Cheonggyecheon Stream is a beautiful place to take a walk and when there are events going on, it’s even better. There is definitely a reason the Cheonggyecheon makes it onto almost every list of top things to see in Seoul.

Whether you’re interested in the eco benefits of the stream, want a pedestrian friendly place to walk through the city in Seoul, or just want a calm place to take a break in downtown Seoul, this is where you should go.
