Siege Battlefield Tunnels
The labyrinth of tunnels known as The Great Siege Tunnels are perhaps the most impressive defence system devised by man.
During the Great Siege, the gallant defenders were stunned when Spanish and French besiegers dug into trenches too close to Gibraltar for the Bristish to fire on them.
Imaginative solutions were needed, and Sgt Major Ince suggested tunneling to get to a projection of rock to allow the Bristish guns to fire sideways on the attackers.
You must purchase a Nature Reserve ticket which will allow you access to other sites like St. Michael’s Cave. We recommend you to purchase a Cable Car Ticket and a Nature Reserve Ticket, both together.
