St. Helena is perhaps best known for housing a very famous prisoner from 1815 - 1821: Napoleon after his final defeat at Waterloo in Belgium. Most of the island has rugged topography, but it is also a popular spot for hikers. Diana’s Peak reaches 818 meters (2,684 feet) high, and it was designated in 1996 as St. Helena’s first national park. The island is part of a remote set of British controlled colonies, which also includes Ascension Island and Tristan da Cunha.
