Panmunjeom

Panmunjom, also known as Panmunjeom, now located in Paju, Gyeonggi Province, South Korea or Panmun-guyok, Kaesong, North Korea, was a village just north of the de facto border between North and South Korea, where the 1953 Korean Armistice Agreement that ended the Korean War was signed. The building where the armistice was signed still stands.

Its name is often used as a metonym for the nearby Joint Security Area, where discussions between North and South Korea still take place in blue buildings that straddle the Military Demarcation Line. As such, it is considered one of the last vestiges of the Cold War.
