but very few people know that there is the zero milestone here. The zero milestone is the starting point of all roads in Korea. The direction and distance of each region are measured based on the zero milestone including Jeongdongjin of Gangwon-do, Jeongnamjin of Jeollanam-do, Dokdo, and the northernmost part of North Korea. I invite you to the zero milestone, which is also the starting point of the Seoul City Bus.
