Relative Location of Seoul
Seoul is located on the Han River. Seoul is also located in the northwestern part of South Korea. If you look at the entire Korean peninsula it is just about in the center. The center of the city is about 37 miles inland from the Yellow Sea which is to the west. Seoul is also just 35 miles from the Demilitarized Zone which separates the Republic of South Korea (ROK) from the Democratic Peoples Republic of Korea (DPRK). This is an important note because a "state of war" still exits between the two countries and this puts Seoul well within artillery and rocket striking range of the DPRK.
Seoul's latitude and longitude is 37º1'North, 126º58'East.
