Yes, truly amazing! Is it possible for anyone to enter that tunnel?

Here in Sweden I have lately heard about the Urban Exploring  
movement. People explore forgotten areas of cities and document these  
odd places on web sites. Stockholm has many tunnels, some that got  
dug out many hundred years ago (that's why we have so many rats here  
but almost never see them on the surface). Nothing like the catacombs  
under Paris of course and not a very impressive acoustic  
reverberation down there. Never the less fascinating.
