Discover the WW2 secret bunker!

Telling the story of the miners who dug into the Porthcurno hillside in 1940, building a secret bunker to house the Telegraph Station during World War II.

To maintain secrecy whilst this ambitious project was underway, curious villagers were told that a shortcut to the local pub was being built. The top secret bunker is now Grade II listed and includes an authentic telegrapher’s workshop and a fully working automated relay station. A secret door leads to the original escape stairs – 120 steps hewn through the solid granite bedrock to the clifftop above, giving a covert way out should the tunnels be overrun.
