Gan
Most of the development in the Seenu atoll and especially in the Gan Island can be attributed to the British. Since the Second World War, the British had established their presence in Seenu Atoll and they developed the island of Gan as a Royal Air Force base. In 1956, the Gan Island became a strategic Cold War outpost. The islands of Gan, Feydhoo, Maradhoo and Hithadhoo were interconnected with causeways. The natives of these islands were employed by the British.
