On the surface it’s England’s largest castle. Dover Castle has been defending the Kent coastline from centuries of invaders since 1066. But below ground it has another hidden side. Deep inside the chalk rocks that make up the White Cliffs of Dover are three miles of underground tunnels that have played their own – more mysterious – part in defending the country.
There aren’t many sights more classically British than the White Cliffs of Dover. They were the first or last sight of home for generations of Britons arriving or leaving the country. And although you’ll more likely find me travelling to Europe high above them by plane or way below by Eurotunnel, what kind of Brit would I be if I’d never seen one of the country’s most iconic sights?
