Port Louis, estimated population 135,371 (1996), is the capital of Mauritius. It is a port on the Indian Ocean, and the nation's largest city. The economy is dominated by its port, which handles Mauritius's international trade. Manufacturing is dominated by clothing and textiles, but also includes chemicals, plastics, and pharmaceuticals. Tourism is also important. The development of the Caudan waterfront, central to Port Louis, with shopping and cinema facilities, appeals to tourists visiting the city.
The Citadel dominates the city. The Mauritius Institute, dedicated to the study of the island's flora and fauna, is in Port Louis.
