Today, I will tell you about Haneul-Gongwon(Park). It means a sky park and located in Mapo-Gu, Seoul. The park was originally a dumping ground for about 20 years. The dirty landfill changed into an ecological park.The park produces gas generated by rotten waste. There are also a lot of reed, so the park is most beautiful in fall. Next to the park, there is a 2002 World Cup Stadium. While walking the park, you can enjoy the scenery in Seoul.
