10 - 2: The Rock

The Tunnels of Gibraltar were a Second World War espionage base, hidden in the Rock of Gibraltar, which lay undiscovered for decades; at Atlas-1 Test Site, are the remains of an ingenious US Airforce project that continues to keep us safe; at Roghudi Vecchio is an ancient culture threatened when an Italian town is deserted; and at Naissaar, a highly classified Soviet munitions factory camouflaged in the forests of Estonia.
