The Korean Demilitarized Zone (DMZ) is a unique strip of land that serves as a buffer between North and South Korea. Established in 1953, it spans approximately 250 kilometres across the Korean Peninsula. Despite its name, it's one of the world's most heavily militarized areas. It's a symbol of both division and unexpected biodiversity, housing several endangered species due to minimal human interference. It's a poignant reminder of the Korean War and the ongoing tension.
