Fun fact

This territory is home to the world's largest marine protected area, encompassing a vast expanse of pristine coral reefs and deep-sea trenches. Due to its remote nature and restricted access, the waters remain virtually untouched by commercial fishing, allowing biodiversity to flourish in an almost prehistoric state. It also hosts the world's most inland-reaching population of coconut crabs, which are the largest terrestrial arthropods on the planet. These giant crustaceans are known to climb trees and possess a pinching force stronger than most land predators.

Currency

The official currency is the United States Dollar (USD), as it is the primary medium of exchange used by the military personnel stationed there. Despite this, the British Pound (GBP) remains legal tender, reflecting a unique dual-currency status rarely seen in other British territories.

Flag symbolism

The flag features the British Union Jack in the canton, signifying its status as a British Overseas Territory. The field is unique among British ensigns, composed of six blue and six white wavy horizontal stripes that represent the waters of the Indian Ocean. On the fly side, a golden palm tree is depicted emerging from behind a crown, symbolizing the tropical vegetation of the islands and royal authority. This combination of maritime waves and botanical imagery distinguishes it from the more traditional solid-color ensigns of other territories.

Emblem history

The coat of arms, which appears on the flag, features a shield supported by two sea turtles—one hawksbill and one green turtle—which represent the local wildlife. The shield itself contains a single palm tree and the St. Edwards Crown, resting above several wavy lines that mirror the flag’s aquatic theme. At the base, the Latin motto 'In tutela nostra Limuria' translates to 'Lemuria is in our charge,' referencing a mythical lost continent once thought to exist in the Indian Ocean. This emblem was formally granted by royal warrant in 1990 to commemorate the 25th anniversary of the territory's establishment.
