Anaa,Nganaa-nui (orAra-ura)[2] is anatoll in theTuamotuarchipelago, inFrench Polynesia. It is located in the north-west of the archipelago, 350 km to the east ofTahiti. It is oval in shape, 29.5 km in length and 6.5 km wide, with a total land area of 38 km2 and a population of 504. The atoll is made up by eleven small barren islands with deeper and more fertile soil than other atolls in the Tuamotus. The lagoon is shallow, without entrance, and formed by three main basins. Although it does not have any navigable access, the water of the lagoon renews by several small channels that can be crossed walking.
The atoll of Anaa was known by the legendary cruelty of its soldiers who in the seventeenth century, dominated the north-west of the Tuamotus.
The Spanish expedition ofPedro Fernández de Quirós landed onConversión de San Pablo on 10 February 1606, since identified as either Anaa or Hao.[3] The sighting of Anaa was recorded by French explorerLouis Antoine de Bougainville in 1768.[4]James Cook sighted it in 1769. Because of its shape, he called itChain Island. Later, Anaa was visited by Spanish explorerDomingo de Bonechea,[5] on November 1 of 1772, who called itIsla de Todos los Santos (All Saints Island) because they arrived onAll Saints' Day.
At the beginning of the nineteenth century, control of the atoll went to the Pomaré of Tahiti. Around 1850 Anaa was an active center of thenacre commerce andcopra, with a maximum population of 2,000. The missionary competition betweenMormons of North America and French Catholics led to a revolt in 1852, and an intervention by French colonial troops.
In 1878 and 1906 Anaa suffered severehurricane damages and was completely flooded. After the hurricane of 1983, the only village was moved and reconstructed, incorporating a refuge shelter with capacity for all its population.
Anaa has aterritorial airport which was inaugurated in 1976.
Anaa is located 66 km south of FaaiteAtoll, 78 km from Tahanea Atoll and 377 km east ofTahiti; and is an oval atoll 29.5 km long and 6.5 km wide, with a total area of 38 km2. The coral reef is made up of eleven islets with deeper and more fertile soil than the other atolls of the Tuamotu, of which nine are named:
Kereteki, Mania, Omanaotika, Oparari, Otepipi, Putuahara, Teharie, Tematahoa and Tukuhora.[6]
The lagoon is shallow, with no navigable passages to the ocean, and consists of 3 main basins. Although it has no navigable passages, the lagoon water is renewed by several shallow channels that can be crossed on foot.
Geologically, the atoll is the coral outgrowth (105 meters) of the top of a large volcanic seamount of the same name (the "Anaa Ridge", 11,438 m3), measuring 3,415 meters from the seafloor, formed some 52.5-59.6 million years ago.[7]
The atoll is home to an endemic population of long-billed warblers and its lagoon has colonies of Cardium fragum.[8]
The main village is Tuuhora, also called Tukuhora or Anaa, with a population of about 350. The other small villages like Temarie, Otepipi, Mania and Tematahoa have small seasonal population. The population subsists mainly on fishing, the cultivation ofnacre and the production ofcopra.
The population was 530 in 2022,[1] and lives mainly from fishing, mother-of-pearl farming and copra production.
In 2017, the total population of Anaa was 494 people[9] and its evolution is as follows:

In 1850, Anaa was an active mother-of-pearl and copra trading centre, with a maximum population of 2000 people. In 1852, French colonial troops intervened, following an uprising resulting from competition between North American Mormons and French Catholics. Today, most of the population is affiliated with Christianity. TheCatholic Church owns a religious building on the atoll (on Tukuhora) called St. Joseph's Church (Église de Saint-Joseph)[10] which is under the Metropolitan Archdiocese ofPapeete based inTahiti.
Most of the atoll'seconomic activity is related to fishing andfish farming, as well as copra production, with coconut plantations cultivated on virtually every motus (islets).
Anaa has anairfield (IATA code: AAA) near the main town of Tukuhora with a runway 1,400 meters long. On average, it handles about 140flights and 3,500 passengers per year.[11]
