Poldark Mine is the only complete tin mine in Cornwall open for underground guided tours and is regarded as one of the most historic locations in the annals of Cornish Mining
Poldark Mine at Wendron is centrally located near Helston on the Lizard Peninsula. The mine is set in four acres of wooded riverside gardens in a beautiful glen on the River Cober valley. The demesne is set in a rural area of Cornwall just 6 miles from the sea. The well-known mine has reopened under new management and as part of the Cornish Mining World Heritage Site has a special place in the story of tin mining. Some consider it to be the veritable cradle of tinning.
