Jamaica is the third largest island in the Caribbean. It lies between latitudes 17° and 19°N, and longitudes 76° and 79°W. Mountains dominate the interior: the Don Figuerero, Santa Cruz, and May Day mountains in the west, the Dry Harbour Mountains in the centre, and the John Crow Mountains and Blue Mountains in the east, the latter containing Blue Mountain Peak, Jamaica's tallest mountain at 2,256 m. They are surrounded by a narrow coastal plain. Jamaica only has two cities, the first being Kingston, the capital city and centre of business, located on the south coast and the second being Montego Bay, one of the best known cities in the Caribbean for tourism, located on the north coast. Kingston Harbour is the seventh-largest natural harbour in the world, which contributed to the city being designated as the capital in 1872. Other towns of note include Portmore, Spanish Town, Savanna la Mar, Mandeville and the resort towns of Ocho Ríos, Port Antonio and Negril.
