Uncovered in 1987 during a scheme to landscape an area of the Great Orme, the copper mines discovered below the ground represent one of the most astounding archaeological discoveries of recent times. Dating back 4,000 years to the Bronze Age, they change our views about the ancient people of Britain and their civilized and structured society 2,000 years before the Roman invasion. Over the past 21 years mining engineers, cavers and archaeologists have been slowly uncovering more tunnels and large areas of the surface landscape to reveal what is now thought to be the largest prehistoric mine so far discovered in the world.
