Port of Spain a shopping and business centre for much of the country. Most government offices are also located in the city and many important government services can only be accessed in the Ministry offices located downtown. Within recent years, local banks headquartered here have helped it become a financial centre for the Caribbean and Central America region. Two of the largest banks in the Caribbean, Republic Bank, Trinidad and Tobago Limited and Royal Bank of Trinidad and Tobago (RBTT, reacquired by the Royal Bank in 2008) are headquartered here or base their Caribbean operations in the city. Trinidad's economy is based on
Port of Spain reclamation of the foreshore mudflats, using fill from the Laventille Hills. This began with the area immediately east of the diverted St. Ann's River; the district is still called Sea Lots today. Gradually the landfill crept west and the area south of Plaza del Marina became solid land. Further major reclamation efforts took place in the 1840s, the 1870s, and in 1906. In 1935 the Deep Water Harbour Scheme dredged the offshore area along Port of Spain's western neighbourhoods, and the dredged material was used to fill in the area south of Woodbrook.
