These are some of the terrifying hidden tunnels underneath Kent - used during some of Britain's darkest hours.
Beneath some of the county's towns are an extensive set of tunnels which were used to shelter from Nazi bombing raids during the Second World War and to prepare for the threat of foreign invasion.
With a number of tunnels located in Broadstairs, Ramsgate and Dover, there is plenty of hidden history, reports Kent Live .
A recently discovered network is underneath a present day Primark at a shopping centre in Thanet.
Hundreds of shoppers have been standing above the tunnels since the store opened in 2011, with no clue as to what lay beneath.
