Tunnel : All The Best Free Flash Games Relating To Tunnel

The word tunnel comes from the French “tonnelle”, meaning a barrel. In olden times, a tunnel was associated to an underpass, usually dug under castles so as to enable its occupants to secretly flee and to be relatively secure.
But tunnels were also built by enemies so as to weaken the outside walls of castles.

Tunnels were hence used for various reasons.
During armed conflicts, these tunnels could also make informations passing on and pedestrians traffic easier. Besides, in Viêt Nam, it is partly because of those underground networks of tunnels called Cù Chi Tunnels that the US army had a dickens of a time to fight in that area.

Today, most tunnels are built so as to avoid destroying an entire forest by cutting it in two, for instance. Tunnels may also be built so as to shorten the route, usually by digging directly mountains to cross them more easily. It is notably possible thanks to state-of-the art technologies: we know exactly where the exit of a tunnel will be by digging into a mountain. This was not the case a century ago. People sometimes dug tunnels thinking they would exit in one place and realized the tunnel led to a ravine.

One of the most fantastic project of tunneling today concerns the collaboration between the USA and Russia to dig a tunnel between Siberia and Alaska. This would be the longest tunnel ever dug: 103 km (around 64 miles).
