Port Louis holds two UNESCO World Heritage sites within 15 km of each other — one where slaves fled to a mountain, one where indentured workers arrived by ship. Between them lie French colonial forts, a Mughal-style citadel and Mauritius's oldest archives.
The stone steps where 462,000 indentured Indians landed between 1849 and 1923, beginning Britain's global 'Great Experiment' after slavery's abolition. UNESCO-listed 2006. Open Mon–Fri 09:00–16:00, Sat 09:00–12:00. Free entry, guided tours on request.
Housed in an 1880s colonial building on the Company Gardens, this holds the world's most complete reconstructed dodo skeleton, assembled from Mare aux Songes bones. The bird was extinct within 80 years of Dutch arrival in 1598. Open Mon–Fri, closed Wed afternoon.
One of the oldest archive collections in the southern hemisphere, with continuous records from 1721 French settlement onward: slave registers, notarial acts, plantation ledgers. Reading room open weekdays 09:00–15:30; bring photo ID to register.
The fifth church on this site since 1756 — earlier versions fell to cyclones in 1773 and 1818 and the 1786 rebuild was demolished in 1929. The current 1932 structure keeps the original bell tower foundations and the Le Réduit-quarried basalt walls.
British-built 1834–1840 on Petite Montagne, in Mughal style by Indian labour, positioned to fire on the town as much as the sea — the garrison feared unrest after slavery's abolition in 1835. Open daily 09:00–17:00, commanding views over the harbour.
The oldest building in Port Louis, begun 1738 under governor Mahé de Labourdonnais, who effectively founded the city as a naval base. The bronze statue facing the harbour dates from 1859. Still the seat of the National Assembly; exterior viewing only.
Mauritius's second UNESCO site, honouring maroons — escaped slaves who lived atop the 556 m basalt monolith. Legend holds some leapt to their deaths in 1835 rather than surrender, unaware slavery had just been abolished. Roughly 75 minutes' drive southwest.
Built 1940 on the slopes above the city as a wartime prayer for peace; Pope John Paul II addressed a crowd here in 1989. The coral-stone terraces climb toward a white Virgin statue overlooking the whole colonial grid of Port Louis.
Chinese traders settled here from the 1780s; the Kwan Tee Pagoda (1842) is the oldest Chinese temple in the southern hemisphere. The quarter's twin friendship gates frame Royal Street, lined with 19th-century shophouses and family-run boutiks.
Built in the 1850s by Indian Muslim merchants, its carved teak doors and Indo-Islamic-meets-Creole facade sit in the middle of the bazaar district. Non-Muslim visitors are generally welcomed outside prayer times; modest dress required.
The tomb of Jacques-Désiré Laval, the French missionary who converted some 67,000 freed slaves after 1841 and was beatified in 1979. His 9 September feast draws pilgrims of every faith across the island — one of Mauritius's largest gatherings.
Port Louis's colonial burial ground, holding graves of French settlers, British officers and the Malagasy and Mozambican dead of the 1866–68 malaria epidemic that killed some 40,000 and pushed the wealthy out to the Plaines Wilhems highlands.
