Margaret Thatcher's plans to open such a mine were halted in 1980 after local campaigning, which included production of The Yellow Cake Revue by composer and conductor Peter Maxwell Davies, who lived on the neighbouring island of Hoy.

Archaeological discoveries In September 2021, archaeologists announced the discovery of two polished stone balls in a 5500 years-old Neolithic burial tomb in Orkney in Sanday.
