Chaguanas  The Borough of Chaguanas is the largest borough (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, 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 the Caroni County. The current mayor is Vandana Mohit, 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. Chaguanas was named for the Chaguanes Amerindian tribe. The area was settled by the time of the British conquest of Trinidad in 1797 (see "History of Trinidad and Tobago"). The town originated on what was then H.E. Robinson's sugar estate adjacent to the Woodford Lodge sugar refinery and the De Verteuil coconut and cocoa estate to the north and east. It was sold over to the now defunct Caroni (1975) Ltd when sugar was the main export commodity for Trinidad and Tobago, and was part of the Woodford Lodge Estate, which is home to several buildings, including the homes of several ex-Caroni workers. Construction of the Trinidad Government Railway helped the town grow. The Princess Margaret Highway, built by the US military during World War II, joined the Southern Main Road at Chaguanas. Construction of the Sir Solomon Hochoy Highway extended the highway south to San Fernando. The Carlsen Air Force Base was a former United States Army Air Forces World War II airbase constructed in Carlsen Field in 1942, consisting of two landing strips, "Edinburgh" and "Xerxes". The airbase also included an emergency landing strip, "Tobago". Edinburgh Field became the principal combat base for USAAF bombers and Naval airships on Trinidad as well as Navy fighters with a complex of runways and taxiways that surpassed even Waller Field. This lasted until 3 November 1943 when, it was renamed Carlsen Field. It was also used by the Royal Air Force and was defended by US Army infantry and AA units.
