San Fernando, Trinidad and Tobago in the context of "José María Chacón"

Port of Spain (Trinidadian English: Port ah Spain [ˈpʊo̯t a ˈspɪe̯n] ) is the capital and chief port of Trinidad and Tobago. With a municipal population of 49,867 (2017), an urban population of 81,142 and a transient daily population of 250,000, it is Trinidad and Tobago's third largest municipality, after Chaguanas and San Fernando.

Port of Spain is located on the Gulf of Paria, on the northwest coast of the island of Trinidad and is part of a larger conurbation stretching from Chaguaramas in the west to Arima in the east with an estimated population of 600,000.

The Borough of Chaguanas is the largest municipality (83,489 at the 2011 census) 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.

Chaguanas became a borough in 1990; prior to that, it was part of Caroni County. The current mayor is Faaiq Mohammed, and the Borough Council has historically been dominated by the United National Congress. Chaguanas has also been a hub for Indo-Trinidadian and Tobagonian culture and even the broader Indo-Caribbean culture.

The village of Moruga lies on the central south coast of Trinidad at the western end of the Trinity Hills. It is in Princes Town region and is served by the Princes Town Regional Corporation.

The village is close to Trinidad's oil reserves, and that and fishing are the area's main economies with some of the residents of the community working in the region's capital Princes Town and San Fernando. It is somewhat of a rural dormitory district for these larger urban areas.

Eugene Chen or Chen Youren (Chinese: 陳友仁; Wade–Giles: Ch'en Yu-jen; 2 July 1878, San Fernando, Trinidad and Tobago – 20 May 1944, Shanghai), known in his youth as Eugene Bernard Achan, was a Chinese Trinidadian lawyer who in the 1920s became Chinese foreign minister. He was known for his success in promoting Sun Yat-sen's anti-imperialist foreign policies.

Arima, officially The Royal Chartered Borough of Arima is the easternmost and second largest in area of the three boroughs of Trinidad and Tobago. It is geographically adjacent to Sangre Grande and Arouca at the south central foothills of the Northern Range. To the south is the Caroni–Arena Dam. Coterminous with Town of Arima since 1888, the borough of Arima is the fourth-largest municipality in population in the country (after Port of Spain, Chaguanas and San Fernando). The census estimated it had 33,606 residents in 2011.

In 1887, the town petitioned Queen Victoria for municipal status as part of the celebration for the Golden Jubilee of Queen Victoria. This was granted in the following year, and Arima became a Royal Borough on 1 August 1888. Historically the third-largest town of Trinidad and Tobago, Arima is fourth since Chaguanas became the largest town in the country.

Couva is a town in west-central Trinidad, south of Port of Spain and Chaguanas and north of San Fernando and Point Fortin. It is the capital and main urban centre of Couva–Tabaquite–Talparo, and the Greater Couva area includes the Point Lisas industrial estate and the port of Point Lisas. It is one of the fastest-growing towns in the country. Couva's southern boundary is at the village of California and Point Lisas, and to the north Couva stretches to McBean (both on the Trinidad Southern Main Road). To the east of Couva is Preysal. To the west of Couva is the road to Waterloo and Carli Bay, which are located on the Gulf of Paria. Couva was part of the Caroni County. Couva is considered a major power base for the United National Congress, whose headquarters was previously located here.
