History
Peros Banhos was discovered in 1513 by
Portuguese navigator
Afonso de Albuquerque
Afonso de Albuquerque, 1st Duke of Goa ( – 16 December 1515), was a Portuguese general, admiral, statesman and ''conquistador''. He served as viceroy of Portuguese India from 1509 to 1515, during which he expanded Portuguese influence across ...
. The name of this atoll derives from "Pêro dos Banhos", the name of another Portuguese navigator who died there after his ship ran aground on this atoll.
The earliest and most interesting description of Peros Banhos was written by Manoel Rangel in ''«A Tragédia dos Baixos de Pero dos Banhos»''. He was a castaway from the
Portuguese ship ''Conceição'' under captain Francisco Nobre that ran aground and was smashed on the Peros Banhos reefs in 1556.
165 survivors were left on a flat sandy island of Peros Banhos before

s were there; among them were two women and five Catholic priests. Rangel mentions that there were weeds and grasses and that about ten thousand birds lived on that Island. While the birds lasted the castaways survived, but they began to die in great numbers after having eaten most of the bird population.
According to Manoel Rangel there was drinking water to be found by digging shallow wells in the sand. Also many turtles came to lay
eggs on the beach of that island.
Since 1756 ÃŽle du Coin was home to a population of up to 500 people. Most of the inhabitants, the
Ilois, were workers in the coconut plantations and in the oil-producing industry. The Ilois were Christian and there were churches and primary schools in Peros Banhos before the local population was moved away. Their language was a
Creole version of French, known as
Chagossian Creole.
There is a small bushy island called ÃŽle Diable on the NW of the atoll.
