The miles of tunnels hidden beneath a Welsh town that lead out to sea

Llandudno’s mine explorers are nearing their goal of breaking through to an unexplored section of the town's Ty Gwyn Copper Mine. The historic Welsh town was once home to miles of tunnels which belonged to a 19th Century copper mine before it was lost to flooding.

In 1985 a group of local mine explorers came together to investigate and promote the history of The Great Orme, which is a Limestone lump that rises 207 metres out of the sea and is referred to as Llandudno’s mini-mountain. The Great Orme is two miles long and one mile wide - and miles of tunnels run beneath Llandudno streets towards it. The group has dedicated their time to hosting underground guided visits to the accessible mines and are continuing to break through to unexplored sections, North Wales Live reports.

For the past 37 years, the Great Orme Exploration Society (GOES) has been learning more about Llandudno’s famous copper mines, and for the past six months there has been a focus on the Ty Gwyn mine, which is separate from the Great Orme. GOES volunteers have worked hard to clear an old rockfall in a ventilation shaft and hope to push on towards the 300-foot-long Tyn y Fron shaft, which is still largely unexplored due to the blockage.
