Seoul Plaza (Taepyeongno, Jung-gu, Seoul) The Seoul Plaza is an elliptical park which is located in front of the Seoul City Hall. It is a usual venue for big events on Korean holidays and is known for its beautiful water fountains and impressive lighting. I haven't seen a lot of Korean dramas filmed here, but sure enough, it's a great attraction for those who go on tours to Korea with family and friends. More pictures under the cut.
