Throughout history, Dover Castle has been a fortress standing guard on the white cliffs of Dover, protecting England from invading troops from the European mainland.
During World War II, its series of underground tunnels were converted into an air-raid shelter and later into a military command center and underground hospital. It was only nine minutes from France by air, so the threat of invasion or attack was always present. These cannons represent just a small sample of what was probably in place during that wartime era.
