Measuring only 2.5 miles wide and 155 miles long (4 kilometers by 250 kilometers), the DMZ, or De-Militarized Zone, is a misnomer; the area is the most fortified border on Earth, with almost a million landmines within its grounds, and numerous bunkers on both sides. The DMZ is the most tangible reminder of the ruinous civil war that was fought on the Korean peninsula from 1950-1953. In the case that Korea is to be reunified, the DMZ will be turned into an ecological park; until that day however, the DMZ remains a flashpoint for conflict, and the North Korean side stands in stark contrast to the south.
Once capital of the Koryo Dynasty (918-1392 AD), Kaesong today is the southernmost city of North Korea. Given its royal pedigree, Kaesong has long been a cultural center, with a highly developed cuisine, considerable numbers of relics, and even several royal tombs. Today, Kaesong is a special zone that has received considerable investment from the South.
