These caves have been visited over thousands of years. The winding underground network has been a limestone quarry, a hiding place for smuggler’s to store their booty and a secret place of worship. The Romans quarried the stone to build their homes and temples. During the Protestant Reformation, Catholics escaped persecution by worshipping here. The notorious smuggler, Jack Rattenbury, was known for hiding his stolen contraband in the cave system. Now tours are available for visitors.
