Seychelles (French: République des Seychelles; Creole: Repiblik Sesel), is an island country spanning an archipelago of 115 islands in the Indian Ocean, some 1,500 kilometres (932 mi) east of mainland Africa, northeast of the island of Madagascar. Seychelles is divided into twenty-five administrative regions that comprise all of the inner islands. Eight of the districts make up the capital of Seychelles and are referred to as Greater Victoria. Another 14 districts are considered the rural part of the main island of Mahé with two districts on Praslin and one on La Digue which also includes respective satellite islands. The rest of the Outer Islands are not considered part of any district. [http://en.wikipedia.org/wiki/Seychelles]
