Port Louis is the capital city of Mauritius. It is mainly located in the Port Louis District, with a small western part in the Black River District. Port Louis is the country's economic, cultural and political centre, and most populous city. It is administered by the Municipal City Council of Port Louis.
Port Louis was already in use as a harbor in 1638. In 1736, under French government, it became the administrative center of Mauritius and a major reprovisioning halt for French ships during their passage between Asia and Europe, around the Cape of Good Hope. The Port is named in honor of King Louis XV. During this period of French colonization, Mauritius was known as Ile de France.
