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.

Carlsen Air Force Base is a former United States Army Air Forces World War II airbase on Trinidad, consisting of two landing strips, "Edinburgh" and "Xeres". The airbase also included an emergency landing strip, "Tobago".
