Senyor in Seoul: Cheonggyecheon Stream 청계천
This place is probably even nicer at night.
We were on our way to Insa-dong (인사동) when we stopped by this place. From what I've read, this was part of an urban renewal project.
The stream already existed but became a neglected one, hidden by an overpass not until it was restored in 2005.
It was a short visit and we were not able to explore the whole stretch of the stream.
We got lost on our way to Insa-dong (인사동) but luckily, we reached Insa-dong PR Center and told us that it was just a block away. They offer renting of Hanbok, the traditional Korean dress, for pictorials as long as you have your own camera with you.
Fortunately, we have cameras with us.
