Olympic Park was one of the places suggested to me to go. It was built in 1988 when South Korea hosted the summer Olympics in Seoul. We really only had time to visit the world peace square.
There is a lot more to do in the park that we didn’t have time for. There’s a cultural section, a fitness section, and a historical section. It also takes somewhere over 3 hours to explore seeing as it’s 1.45 million ㎡.
