Bridgetown is the capital and largest city of the nation of Barbados. The Bridgetown port, found along Carlisle Bay lies on the southwestern coast of the island. Bridgetown is a major West Indies tourist destination, and the city acts as an important financial, informatics, convention centre, and cruise ship port of call in the Caribbean region. Bridgetown´s centre was originally composed of a swamp, which was quickly drained and filled-in to make way for the city´s early development. At the heart of Bridgetown is the Careenage and Constitution River.This body of water provides the city with direct access from medium sized yachts or small craft boats. Although moderately shallow, the Careenage slices Bridgetown into two parts. During the rainy season the Constitution River flows into the Careenage area and acts as an outflow for water from the islands interior storm drainage network. Flowing into the Carlisle Bay on the southwest coast of the island, the Careenage can be observed as a marina for boaters entering or exiting the inner basin located directly in front of the Parliament buildings of Barbados. In the centre lies the main street of Bridgetown which is Broad Street which runs directly through the centre of the city. Broad Street passes the Parliament Buildings and serves as the centre of city´s shopping area.
