Roman Catholic Diocese of Port-Louis

St. Louis Cathedral (French: Cathédrale Saint-Louis de Port-Louis, Mauritian Creole: Katedral Sin Lwi) is a Roman Catholic cathedral in Port Louis, Mauritius, the seat of the bishop of Port-Louis.Several churches have been built in succession at this location. Between 1752 and 1756, Joseph-François Charpentier de Cossigny built the first, which soon fell apart, and then was hit by a cyclone in 1760. A new church collapsed again on April 9, 1773 as a result of another cyclone. A further reconstruction in 1782 soon ended in collapse. Subsequently, the building was restored in 1814 by Sir Robert Townsend Farquhar, the first British governor, until the same recurring structural problems reappeared in 1819. Bishop Jacques Leen rebuilt the structure from 1930 to 1933, and a final restoration was completed in 2007.

Prior to 1968 and under British rule it was known as the Legislative Council. The Constitution of Mauritius provides for the parliament of Mauritius to consist of the President and the National Assembly. The parliament of Mauritius is modelled after the Westminster system of parliamentary democracy, where members of parliament are voted in at regular general elections, on the basis of a first past the post system. The working language of the National Assembly is English. It consists of 70 members, 62 directly elected for five-year terms in multi-member constituencies and 8 additional members, known as "best losers", appointed by the Electoral Supervisory Commission to ensure that ethnic and religious minorities are equitably represented. The Government is primarily responsible to the National Assembly and the prime minister stays in office with the confidence of a majority of its members.

The Champ de Mars Racecourse (French: Hippodrome du Champ de Mars) is a thoroughbred horse race track in Port Louis, Mauritius. The Racecourse was inaugurated on 25 June 1812, by The Mauritius Turf Club (MTC) which was founded earlier the same year by Edward Alured Draper, who served in different capacities, namely as Chief of Police, Colonial Secretary, Collector of Customs, Civil engineer, Registrar of Slaves, Magistrate and Colonial Treasurer. The Mauritius Turf Club is the oldest horse-racing club in the Southern Hemisphere and the second oldest in the world. The race track follows a very selective right hand oval path and is relatively small in size, with a circumference of 1,298 meters (4,258.5 ft) and width between 12 and 14 meters (39 and 46 feet). The home-straight extends uphill and is 225 meters (738 ft) long. When Mauritius gained independence on 12 March 1968, the event including the flag hoisting ceremony was held here. Since then and for many years, the racecourse has seen the annual celebration of the accession to independence. Today, the Champ de Mars attracts tens of thousands of people on each racing day during the racing season from late March to early December and has become the ultimate meeting place for racing fanatics from all over the island and even from abroad. The track has also played a fundamental role in propelling horse racing as the most popular sport and form of entertainment among the local population.

The Immigration Depot (Hindi: आप्रवासी घाट, ISO: Āpravāsī Ghāta) is a building complex located in Port Louis on the Indian Ocean island of Mauritius, the first British colony to receive indentured, or contracted, labour workforce from many countries. From 1849 to 1923, half a million Indian indentured labourers passed through the Immigration Depot, to be transported to plantations throughout the British Empire. The large-scale migration of the labourers left an indelible mark on the societies of many former British colonies, with Indians constituting a substantial proportion of their national populations. In Mauritius alone, 68 percent of the current total population is of Indian ancestry. The Immigration Depot has thus become an important reference point in the history and cultural identity of Mauritius. Unchecked infrastructural development in the mid-20th century means that only the partial remains of three stone buildings from the entire complex have survived. These are now protected as a national monument, under the Mauritian national heritage legislation. The Immigration Depot's role in social history was recognized by UNESCO when it was declared a World Heritage Site in 2006. The site is under the management of the Aapravasi Ghat Trust Fund. Conservation efforts are underway to restore the fragile buildings to their 1860s state. It is one of two World Heritage Sites in Mauritius, along with Le Morne Brabant.
