Today we explored the Cheong Gye Cheon stream. It dates back to the 1300's and used to be where the housewives did their laundry. In the early 1900's it became a shanty town. In an effort to improve the area in 1958 the stream was covered with concrete and in 1976 an elevated highway was built over it. In 2005 the Cheonggyecheon stream was restored to a park like setting. It is an nice area to walk through, even though it was very cold when we did.
