The DMZ, or Demilitarized Zone, is a buffer area between North Korea and South Korea. Established in 1953 after the Korean War, it stretches approximately 160 miles across the Korean Peninsula. The zone is about 2.5 miles wide and serves as a barrier to prevent military conflict between the two countries. Despite its name, the DMZ is heavily fortified and monitored by both sides. It is one of the most militarized borders in the world, with troops, surveillance equipment, and barriers. The area is also home to unique wildlife, as human activity is limited, creating a rare ecosystem.
