Basset Mines, Cornwall
The Cornwall and West Devon Mining area was granted World Heritage status on 14 July 2006. Surviving buildings include the Marriott's Shaft complex of South Wheal Frances, West Basset Stamps and Wheal Basset Stamps. The West Basset Stamps, which had a secondary beam engine to pump water for dressing, stands over an unusually fine example of a 19th-century tin dressing floor. The Marriott's Shaft complex includes the pumping engine house, which held the only inverted beam engine in Cornwall, the houses for the winding, compressor and crusher engines, and the miners' dry.
