Recommendation by Jica Simpas
Beautiful piece of atypical architecture by architect Zaha Hadid. There are no corner surfaces or straight walls. It's a huge place but points of interest are the Design Market, where you can buy different creative trinkets (I got a bunch of stuff, and I love them all); or the Art Hall, Museum, and Dongdaemun History and Culture Park to learn about Korea. We went during the afternoon, but I've heard it looks even better at night... or when it's not so gloomy.
