Cheonggyecheon Stream

The original Cheonggyecheon Stream was a long stream
that predated the city of Seoul. The stream connected
connected the nearby mountains to the Hangang river.
During the Joseon Dynasty, the stream was known as
Gaecheon, meaning open stream. King Taejong, who
reigned from 1400 to 1418, strengthened the banks
of the stream and built its iconic bridges. Refurbishment
work became a national project during the reign of
King Yeonjo, who ruled from 1724 to 1776. Created
as part of an urban renewal project, Cheonggyecheon
is now an 11 km long modern stream that runs through
downtown Seoul.
