Makatea, or Mangaia-te-vai-tamae, is a raised coral atoll in the northwestern part of the Tuamotus, which is a part of the French overseas collectivity of French Polynesia. It is located southwest from Rangiroa to the west of the Palliser group, which also is in French Polynesia. Makatea is surrounded by spectacular cliffs, rising to a plateau above sea level. This island is long, with a maximum width of in the south. It is in area. Makatea is one of the only four islands of the Tuamotu Archipelago (along with Nukutavake, Tikei, and Tepoto Nord) that do not take the form of a typical atoll. Makatea is one of the only Paumotuan islands with potable water. Its native name derived from the drinking water being brought out of its dark caves by the local people. "Mā," pure, clear; used here to mean water, "Atea," light of day and "K" for euphony. The other name of the Island was Mangaia-te-vai-tamāe, meaning "Mangaia of the purified (or clear) water." The island was called "Sagitario" in 1606 by Pedro Fernandes de Queirós who led a Spanish expedition to Terra Australis from Peru. Over a century later it was named "Aurora" by Dutch mariner Jakob Roggeveen in 1722. Later, the Polynesians called it "Papa Tea" (which means "white rock"). There is a ghost town, Vaitepaua, and an adjacent abandoned port, Temao, on the northwest coast of Makatea. These are from the times of phosphate mining (1917 to 1964). Makatea is one of three important Pacific raised coral islands that had large phosphate deposits, the other two being Nauru and Banaba. The Pacific Phosphate Company Ltd, (PPC), which was founded by John T. Arundel and involved in mining at Nauru and Banaba, formed the Compagnie des Phosphates de l'Océanie with a Tahitian syndicate to mine phosphate on Makatea. In September 1909, , a ship owned by the PPC, was wrecked on the reef at Makatea; a bent connecting rod caused the engines to stop and the current carried the ship onto the reef. Phosphate mining drew hundreds of people to Makatea in the years before the French Centre d'Experimentation du Pacifique (CEP) started nuclear experiments.
