Former Portuguese colony, Sao Tome and Principe is an archipelago in the South Atlantic in the Gulf of Guinea, 350 kilometers of Gabon. The archipelago consists of two large volcanic islands, the island of St. Thomas (Sao Tome) and Prince's Island (Principe), as well as small islands and islets. The island of St. Thomas was named after the day of its discovery: it was accosted December 21, 1471, the day of Saint Thomas by Portuguese sailors João de Santarem and Pedro Escobar. The smallest African country (850 km2 and Principe: 130 km2) is independent of Portugal since 1975. It always speaks mostly Portuguese, but also the Creole and English. The population of the archipelago is estimated at 165,000 Saotoméens.
