Dongdaemun Design Plaza in Seoul has a large exhibition space which is continously changing. I was able to go to this exhibition, 'teamLab: LIFE,' before it closed. With multiple different rooms, all with dazzling displays of nature, this attraction was very popular amongst the youth. Exhibitions seem to be very popular in Seoul, and they are always changing, meaning you will get various unique experiences every time. It's a great rainy day activity, as well as a great thing to do with friends. Specifically for people that like to take pictures, these attractions are great! I highly reccommend these kinds of interactive exhibits when you visit Seoul!!
