Geevor Mine is a large preserved twentieth century tin mine, and is the principal visitor facility within the district. The site occupies a shallow sloping valley which meets the sea at Trewellard Zawn. It is dominated by the tall Victory Shaft steel headgear (1954) which forms a prominent land and seamark.

As well as retaining a very high proportion of its machinery, the site also incorporates eighteenth century underground workings, mid-nineteenth century mine structures and a well-preserved Brunton calciner (1912, Scheduled Monument), all of which are embedded in a tin mill complex whose development spans most of the twentieth century.
