Saint Lucia, island state in the Caribbean Sea. It is the second largest of the Windward group in the Lesser Antilles and is located about 24 miles (39 km) south of Martinique and some 21 miles (34 km) northeast of Saint Vincent.
Saint Lucia is 27 miles (43 km) long and has a maximum width of 14 miles (23 km). The capital and major port is Castries. Saint Lucia is a member of the Commonwealth.
The island is of volcanic origin and is bisected from north to south by a central ridge of wooded mountains, the highest point being Mount Gimie (3,145 feet [959 metres]). Many streams flow from the mountains through fertile valleys. In the southwest are the Gros and Petit Pitons (2,619 feet [798 metres] and 2,460 feet [750 metres], respectively), two immense pyramids of rock rising sharply from the sea and enclosing a small bay. Near Petit Piton, in the crater of an ancient volcano, are the boiling sulphur springs from which the nearby town of Soufrière takes its name. A choice tourist site, the springs also contain substantial energy potential.
o Caribs remain on the island; the vast majority of the inhabitants of the island are black and there is a small minority of mulattoes and other mixtures. The remainder are whites or of East Indian extraction. A French patois is spoken by most of the inhabitants but is being gradually supplanted by English, the official language. The main religion is Roman Catholicism, and Seventh-day Adventists and other Protestants are important minorities. The rate of population growth for Saint Lucia is slightly higher than the Caribbean average. The main population centres are Castries and Vieux Fort.
