St Just Mining District
The St Just Mining District contains some of the most dramatically located mines and structures of any Area of the World Heritage Site.
Botallack and Levant mines on the north coast had shafts positioned at the cliff edge to facilitate access to ore bodies that occur at the margins of the granite and ‘killas’ (Upper Devonian slate) contact, and which extend under the Atlantic. Both Engine and Boscawen’s Shafts within the Crowns section of Botallack mine are located some way down the cliff thereby lessening the effort, time and expense required to sink them. The engine houses constructed here are probably two of the most iconic features associated with Cornish mining.
