- The DMZ is a 2 km-wide buffer, stretching coast to coast across the peninsula, lined by both sides with razor wire, heavy armaments and tank traps.
- It is 60 km (37 miles) from Seoul and 210 km (130 miles) from the North Korean capital of Pyongyang.
- Inside the DMZ is a Joint Security Area (JSA). The so-called peace village of Panmunjom, where the armistice that halted the Korean War was signed in 1953, is located in the 800-metre-wide and 400-metre-long JSA zone.
- A Military Demarcation Line (MDL) marks the boundary between the two Koreas.
- Panmunjom is a cluster of distinctive bright blue buildings. The two Koreas have their own liaison offices and conference halls, on each side of the MDL in Panmunjom.
- Under a 1953 deal, the U.N. Command and the North Korean military were allowed to dispatch no more than 35 troops to the JSA, and each of them can only possess one pistol or non-automatic rifle. But the number of soldiers and weapons increased as relations worsened.
- The troops face each across the MDL in Panmunjom.
- The first inter-Korean summit in more than a decade was held in Panmunjom last year.
- After a third summit between the two Koreas in September, the two sides withdrew firearms from the JSA and cut the number of troops back to the original 35.
- Vast stretches of the DMZ have been no man’s land for more than 60 years, where wildlife has flourished undisturbed. Other parts of it offer an unsettling mix of military installations and tourist attractions.
- According to the U.N. command, more than 105,000 tourists visited the JSA from the South in 2017, while nearly 30,000 visited from the North.
