Here’s something you probably didn’t know about the White Cliffs of Dover. Inside the cliff above the town of Dover lies a shaft carved through the rock, with three concentric spiral staircases. These were built between 1806 and 1809 in order to get troops down to the harbor in a hurry. Take a look at this marvel of engineering at deputydog. http://deputy-dog.com/2008/02/04/the-grand-shaft-amazing-military-engineering/
