St Just is one of the most ancient mining districts in Cornwall and remains of ancient pre-industrial and more modern mining activity have had a considerable impact on the nearby landscape. The area was during the 19th century one of the most important mining districts in Cornwall both for copper and tin. Mines within the area included Levant Mine, Botallack, and Geevor Tin Mine (which closed in 1990) It was announced in July 2006 that the St Just mining district and the rest of the historic mining areas of Cornwall had become the Cornwall and West Devon Mining Landscape World Heritage Site.
