Cayenne is an important seaport in South America. The major port of Dégrad des Cannes is on the estuary of the river Mahury, replacing Larivot and the Îles du Salut. Timber, rosewood essence, rum, and gold are exported in small quantities. In the mid-1960s sugarcane and pineapple were planted around the city, and a pineapple cannery and a shrimp-processing plant were later built. A seafront avenue links Cayenne with the suburbs of Chaton and Montabo, where the French Institute of Tropical America and the Pasteur Institute are located. Historic landmarks include the Church of the Holy Saviour and a prefecture on the Place d’Armes. The Félix Eboué International Airport is the only international airport serving Cayenne.
