3. Seoul has been a capital city since 1394, during the Joseon Dynasty
Seoul was first settled in 554 and was originally known as Hanyang. It was renamed Hanseong in 1392 and became the capital of the Yi Dynasty in 1394.
Seoul was also a capital in 18 BC under the Baekje Kingdom. Over the years, Seoul has had several names, including Wiryeseong, Namgyeong and Gyeongseong, but the city became known as Seoul after World War II.
The name Seoul comes from a Korean word that originally meant “capital city.” It likely evolved from Seorabeol, the name of Silla’s capital.

5. Seoul is only 35 miles from the border with North Korea
Seoul is located only 35 miles from the border with North Korea, near the Joint Security Area. Despite the proximity, most South Koreans don’t think much about the situation with North Korea in their daily lives.
Tourists can take trips from Seoul to the Joint Security Area and other important spots along the Demilitarized Zone (DMZ), including underground tunnels built by North Korea, which are now open for exploration.
Travel between Seoul (South Korea) and Pyongyang (North Korea) is not possible due to political and military tensions between North and South Korea after the Korean War.
Korean War (June 1950 – July 1953)
The Korean War was a proxy conflict after Korean independence from Japan.
At the conclusion of World War II, Korea had been a Japanese colony for 35 years. The Soviet Union and the United States divided the nation into two occupation zones at the 38th parallel. The zones formed their own governments, and each made plans to unite, but under their respective methods of governance.
The 625 War, as it’s known in South Korea, pitted North Korea, backed by China and the Soviet Union, against South Korea, supported by the United States and a coalition of United Nations forces.
The war ended with an armistice, or agreement to end hostilities and a demarcation at the 38th parallel.

In 1977, the Seoul Metropolitan Government proposed an exchange of street names with Tehran to honor the visit of Tehran’s mayor, Gholamreza Nikpey.
In 1978, Samneungno Street in Seoul was renamed Teheran-ro. Tehran-ro in present-day Seoul is a major street through Gangnam.

The January 21st Incident / Blue House Raid
On January 21, 1968, 31 North Korean operatives infiltrated Seoul in a raid on the Blue House to assassinate President Park. This event is known as the “January 21 Incident” to Koreans or the Blue House Raid overseas.
