Tristan da Cunha: The island group consists of the islands of Tristan da Cunha, Nightingale, Inaccessible, and Gough. Tristan da Cunha is named after its Portuguese discoverer (1506); it was garrisoned by the British in 1816 to prevent any attempt to rescue Napoleon from Saint Helena. Gough and Inaccessible Islands have been designated World Heritage Sites. South Africa leases a site for a meteorological station on Gough Island.
