Montserrat ( /mɒntsəˈræt/) is a British overseas territory located in the Leeward Islands, part of the chain of islands called the Lesser Antilles in the West Indies. This island measures approximately 16 km (9.9 mi) long and 11 km (6.8 mi) wide, giving 40 kilometres (25 mi) of coastline. Montserrat is nicknamed the Emerald Isle of the Caribbean both for its resemblance to coastal Ireland and for the Irish ancestry of some of its inhabitants.
