Egmont Atoll

The Egmont Islands or Egmont Atoll, also known as Six Iles, is an uninhabited atoll administered by the United Kingdom. They are one of the few emerged coral that make up the Chagos Archipelago, British Indian Ocean Territory.

This small atoll lies less than 10 km south of the southwestern rim of the Great Chagos Bank submerged coral reef. The nearest island is Danger Island on the Great Chagos Bank, less than 30 km due north. Its total size is 29 km², including the lagoon and the fringing coral reef. The land area totals about 4 km².

There are two passages into the lagoon along the Northern Rim, Fausse Passe in the northeast and a wider passage in the northwest. The Egmont Islands are one of the favorite anchoring spots for itinerant yachtsmen passing through the Chagos.

The largest island is "Île Sud-Est" (Eastern Egmont), where the settlement was located, with an area of 1.5 km². While "Île Lubine" is similar in size, the other islets are smaller. All islands are covered with coconut trees. The individual islands are all on the southern rim of the coral reef. They are, from southeast to northwest:

West of Ile aux Rats there was a small islet known as Ilot aux Rats (Ile des Rats) which has now merged with Ile aux Rats. Ile Cipaye is also spelled 'Sipaille' and 'Cipaille'. Isle Carre Pate is also spelled 'Carpathe'. On some maritime charts Ile Takamaka is spelled as 'Tattamucca'.

Ile Sudest, the largest island, was first settled in the last half of the 18th century, at the time when the other atolls of the Chagos were settled by the French.

Commander Robert Moresby made a survey of this atoll and charted it in 1838. At that time there was a coconut plantation on this atoll. A causeway had been built linking the islands and some land reclamation was done. Eventually some of the islands merged with each other.

The Egmont Islands were no longer inhabited in the second half of the 20th century, at the time that the Chagossians or Ilois were evicted from the Chagos.
