"São Tomé and Príncipe, officially the Democratic Republic of São Tomé and Príncipe, is a Portuguese-speaking island nation in the Gulf of Guinea, off the western equatorial coast of Central Africa. It consists of two archipelagos around the two main islands: São Tomé and Príncipe, located about 140 kilometres apart and about 250 and 225 kilometres, respectively, off the northwestern coast of Gabon.

It was named in honour of Saint Thomas by Portuguese explorers who arrived at the island on his feast day. ..."
