The Labrador Secret Tunnels aren't really a secret any more. They're still worth a visit, especially if you're a history buff. These abandoned tunnels were used by the British Army during World War II and were rediscovered only recently in 2001, when the Labrador Nature Reserve was being established.
The tunnels are linked to a number of casements that used to serve as posts for 6-inch guns and machine-guns. Tour guides are on hand to provide commentary, explaining the routines used by British forces to handle explosions and fires that break out during an attack.
A great deal of effort has been taken to preserve the tunnels in their original form. Multimedia and interactive presentations have been also been added to recreate a wartime experience.
