Great Siege Tunnels 
Description
These were built during the great siege of the late 18th Century, by the forerunners of the Royal Engineers, to help defend the rock from attack. They now form part of over 50Km of passages and tunnels that cover the rock, more inside the rock than there are roads on the outside! As you explore the tunnels you travel right through the centre of the rock with the final tunnel opening out onto the East side of the rock (you enter on the West side)
