Tristan da Cunha /ˈtrɪstən də ˈkuːnjə/, colloquially Tristan, is both a remote group of volcanic islands in the south Atlantic Ocean and the main island of that group. It is the most remote inhabited archipelago in the world, lying 2,000 kilometres (1,200 mi) from the nearest inhabited land, Saint Helena, 2,400 kilometres (1,500 mi) from the nearest continental land, South Africa, and 3,360 kilometres (2,090 mi) from South America. The territory consists of the main island, also named Tristan da Cunha, which has a north–south length of 11.27 kilometres (7.00 mi) and has an area of 98 square kilometres (38 sq mi), along with the smaller, uninhabited Nightingale Islands and the wildlife reserves of Inaccessible and Gough Islands.
