see is what
here's what I saw on the side of INHABITAT, amazing.
Stumień that divided the north-south Seoul, was "created" by the Joseon Dynasty to water the city. With time, Seoul has absorbed stumień and covered it in 1971, a busy road. In 2003 it was decided to liquidate the road and the discovery of a stream, which proved to be stinking sewage. For a total of 281 mil.USD revitalized the 5.8 km stream, giving the city a place to rest. The temperature of land surrounding the stream is lower by 3.6 C, which already makes it a very attractive place in the city center. Interesting is also the last digit. Namely, 75% of the material to consolidate and build a new green paths from the highway once rozbórki covering the stream.
