Uncovered in 1987 on Llandudno's Great Orme, the copper mines discovered are one of the most astounding archaeological discoveries of recent times. Dating back 4,000 years to the Bronze Age they increased our knowledge about the ancient Britons and their civilized, structured society that existed 2,000 years before the Roman invasion.
Over the past 28 years mining engineers, cavers and archaeologists have been slowly uncovering 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.
