The Demilitarized Zone is a 4-kilometer-wide buffer zone that runs across the Korean Peninsula, established after the 1953 armistice ending the Korean War. It is one of the most heavily fortified borders in the world, with military installations, watchtowers, and landmines throughout. Despite its name, it is one of the most militarized zones on Earth, yet it has become an unexpected sanctuary for wildlife due to minimal human activity.
