Futuna is an island in the Pacific Ocean belonging to the French overseas collectivity of Wallis and Futuna. It is one of the Hoorn Islands or Iles Horne, nearby Alofi being the other. They are both a remnant of an old extinct volcano, now bordered with a fringing reef. The island is famous as the place (where the cathedral of Poi now stands) where Pierre Chanel was martyred in 1841, becoming Polynesia’s one and only Catholic saint.
Futuna’s highest point is Mont Puke with 524 m, and the island has an area of 83 km, with 53 km in Sigave and 30 km in Alo (Alo).
