The capital, near the southeastern tip of Grande Terre, overlooks one of the world’s largest sheltered natural harbors. Nouméa is a busy little city with a population composed of many racial groups: French, Melanesian, Polynesian and Vietnamese, amongst others. The main square, the Place des Cocotiers, has undergone extensive restoration. Minibuses, the Nouméa Explorer and Le Petit Train are probably the best ways of seeing the city and its suburbs. The center of the network is the bus station on the Place des Cocotiers. Attractions in the city include St Joseph’s Cathedral, museums, the market, many old colonial houses and the Aquarium, one of the world’s leading centers of marine scientific research. Nearby, the South Pacific Commission Building houses a collection of native handicrafts from all over the South Seas. The New Caledonia Museum is open Tuesday to Saturday, and also contains many local handicrafts and ornaments. The new Museum of Maritime History (whose exhibits include artifacts from numerous local wrecks) is situated by the port in Nouméa. The Tjibaou Cultural Center in Nouméa is a new venue for concerts, plays and exhibitions celebrating indigenous cultural traditions.
