The former borough was elevated to the status of a city corporation on 18 November 1988. The motto of San Fernando is: "Sanitas Fortis" - In a Healthy Environment We Will Find Strength. San Fernando is called Trinidad and Tobago's "industrial capital" because of its proximity to the Pointe-à-Pierre oil refinery and many other petrochemical, LNG, iron and steel and aluminium smelters in places such as Point Lisas in Couva, Point Fortin, and La Brea.
The Borough of Chaguanas is the largest municipality and fastest-growing town in Trinidad and Tobago. Located in west-central Trinidad, south of Port of Spain, north of Couva and San Fernando, and named after the indigenous tribe who originally settled there, it grew in size due to its proximity to the Woodford Lodge sugar refinery. It remained a minor town until the 1980s when it began to grow rapidly as it drew people for its bargain shopping and moderately priced housing. Its rapid growth has seen property values increase dramatically, however.
