Beneath every city there is a complex system of tunnels that remain a mystery to the majority of inhabitants above. Many of us are curious about what’s down there, but few are willing to find out for themselves. Thank goodness for people like photographer Steve Duncan who’s willing to go where most wouldn’t dare. Click on the images to see which cities these tunnels wind below.
