Visiting Fan Bay Deep Shelter
Experience the adventure of a hard hat, head torch lit tour of this incredible time capsule hidden beneath The White Cliffs of Dover.
Fan Bay Deep Shelter is a tunnel complex constructed in 1940/41 as accommodation for the gun battery above. Today this network of abandoned tunnels is virtually all that remains of these long forgotten defences.
You too can experience the incredible adventure underground. Take a journey into the past on a guided tour of the tunnels with one of our expert volunteers, peering into the darkness and back in time into a different world, hidden within the cliffs.
The tunnel tour also includes a chance to see two sound mirrors, First World War early acoustic warning devices, up close and find out more about them.
