Worlds Awesomest Tunnels
Henan Province, China
Thirteen villagers carved 3/4 of a mile into the side of a mountain because their tiny hamlet was cut off from the rest of the world save for a breakneck climb up a 700 step staircase. It took them five years. Thirteen villagers. With hand tools. I don t know if that s more impressive than the sheer natural beauty of the Taihang mountains but, I mean, it s close right?
