Wow – this is a fascinating look at what is going on underground. Unfortunately, there is no location listed – although I notice that the signs inside are in multiple languages – so this might actually be in Europe. Some things I thought notable were that not all of the tunnels are lit up – long sections are completely in the dark. Also – there are offshoots at various places – one which is clearly behind a very large safe-like door (bomb proof?). The entire length of this run is paved – and it appears to go for miles. I wonder what protocols were broken getting this footage out of the tunnel?
