Tristan da Cunha, the Loneliest Island on Earth
When Napoleon was sent to St. Helena by the British, they annexed the closest chain of islands to prevent the French from attempting to rescue him. After all, who wouldn't travel a mere 2430 km over rough and hostile seas in order to rescue the Emperor himself? Yes, that's right, the islands of Tristan Da Cunha closest neighboring land mass, the island of St. Helena, is 2430 km away.
The island is so small that cartographers can't even put it on their maps (not enough resolution). Located in the South Atlantic between Africa and South America, this volcanic outcropping has the honor of being the remotest inhabited island on the planet, and that's including Antarctica and the North Pole. One of the islands in the archipelago is called "Inaccessible", which only seems appropriate, together with their motto: "Our faith is our strength"
