The African Banks are the uninhabited northernmost islands of the Amirante Islands, of the Outer Islands of the Republic of Seychelles, in the western Indian Ocean.
The islands were discovered in 1797 and named Γlots Africains by Admiral Willaumez commanding the frigate La RΓ©gΓ©nΓ©rΓ©e. N
The African Banks lie about 230 km west of the city of Victoria on the main Seychelles island of MahΓ©, close to the edge of the Amirantes Bank. The nearest island is Remire Island, lying 27 km south. The group is a pseudo-atoll, has two small islands, which are gradually undergoing coastal erosion, and appear as just small sandstone ridges exposed only at low tide. The underwater banks extend over 4 kilometres (2.5 miles) north-south and 3 kilometres (1.9 miles) east-west and occupy a total area of about 10 square kilometres (3.9 square miles). With a shallow coral ring, it appears as an incomplete atoll. To the west of the coral ring, however, it is 19 to 36 metres (62β118 feet) deep.
The island group includes: D'Arros, Descroches, Poivre, Remire (Eagle), Marie Louise.
