Secrets of Ramsgate's wartime underground tunnels

Most people think of Dover as being the most important town on the front line during World War Two, but nearby Ramsgate also played a significant role in the defence of the UK.
Yet many of the town's wartime secrets lie buried and forgotten deep below the ground.
Sixty feet underneath the town of Ramsgate lies a network of tunnels extending for three and a half miles.
The tunnels were dug in just nine months at the beginning of World War Two, using mostly picks and shovels.
During World War Two they became a refuge, a secret underground town providing shelter from air raids for 26,000 people.
Famous visitors included Prime Minister Winston Churchill who came to Ramsgate to inspect bomb damage but was forced to descend into the tunnels for shelter during an air raid.
The tunnels were abandoned for nearly 70 years but now Phil Spain and the Ramsgate Tunnels' Team have been working on a project to restore them.
Inside Out meets Phil to hear about the forgotten history of Ramsgate's underground wartime labyrinth.
