Rotuma is a self-governing heptarchy, generally designated a dependency of Fiji. Rotuma commonly referred to Rotuma Island, the only permanently inhabited and by far the largest of all the islands in the Rotuma Group. Officially, the Rotuma Act declares that Rotuma consists of Rotuma Island as well as its neighbouring islands, rocks, and reefs across the entire Rotuma Group. The dependency is situated around 500 km west of the French islands of Wallis and Futuna and a similar distance north of the Fijian mainland. Its capital is Ahau, a hamlet consisting of a number of colonial-era buildings. Rotuma exists as a dependency of Fiji but itself contains its own socioreligious pene-enclave known traditionally as Faguta where the chiefs and their villages adhere to the practices of worship, festival dates, and French-based writing system of the Marists, based at Sumi.
