Second Tunnel

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.
