[2] The mansion was used as the home of the governor of Trinidad and Tobago from 1876 to 30 April 1958, when it became the residence of the governor-general of the West Indies Federation.

The mansion was then used as a museum and art gallery for a period, until it again became the residence of the governors-general.

When Trinidad and Tobago became a republic in 1976, the governor-general's mansion was subsequently designated as "The President's House", and became the residence of the president of the Republic of Trinidad and Tobago.

Today, as well as being the president's private residence, the mansion is used for national awards and swearing-in ceremonies, as well as diplomatic receptions.

The president's office is located in a separate building on the grounds of the mansion.
