Havana Harbor is the port of Havana, the capital of Cuba, and it is the main port in Cuba (not including Guantanamo Bay Naval Base, a territory on lease by the United States). Most vessels coming to the island make port in Havana. Other port cities in Cuba include Cienfuegos, Matanzas, Manzanillo and Santiago de Cuba.
The harbour was created from the natural Havana Bay which is entered through a narrow inlet and which divides into three main harbors: Marimelena, Guanabacoa, and Atarés.
A lighthouse is a tower, building, or other type of structure designed to emit light from a system of lamps and lenses and used as an aid to navigation for maritime pilots at sea or on inland waterways.
Lighthouses mark dangerous coastlines, hazardous shoals, reefs, safe entries to harbors, and can also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and replacement by modern electronic navigational systems.
