The 3rd Tunnel of Aggression, discovered in 1978, is one of the most famous infiltration tunnels beneath the Korean Demilitarized Zone (DMZ). Dug by North Korea, it was intended as a secret passage for a surprise invasion of the South, large enough to move an entire regiment per hour. Today, you can descend deep underground to waddle through a portion of this remarkable and unsettling reminder of Korea’s divided past. An interesting fact: the tunnel stretches over 1.6 kilometers and lies just 44 kilometers from Seoul, highlighting how close conflict once came to the capital. Outside, beyond the exhibition hall, you’ll find a peaceful contrast, a serene garden area with benches and trees that symbolize hope and reconciliation. Somewhere near a tree trunk, a small penguin stone now stands guard, watching over the DMZ’s quiet landscape, a playful symbol of peace in a place once built for war.
