Second Tunnel

Tunnel in Cheorwon

Dug by North Korea in 1975, about 1km of this tunnel lies in South Korea and it’s large enough for purportedly 16,000 soldiers to stream through per hour. A 150m staircase leads down to the tunnel, then it’s a well-lit, albeit damp, 500m stretch to where the tunnel was discovered, just 300m from the border.
