Havana ( , IPA: aˈβana, officially Ciudad de La Habana,) is the capital city, major port, and leading commercial centre of Cuba. The city is one of the 14 Cuban provinces. The city/province has 2.4 million inhabitants, and the urban area over 3.7 million, making Havana the largest city in both Cuba and the Caribbean region. The city extends mostly westward and southward from the bay, which is entered through a narrow inlet and which divides into three main harbours: Marimelena, Guanabacoa, and Atarés. The sluggish Almendares River traverses the city from south to north, entering the Straits of Florida a few miles west of the bay.

King Philip II of Spain granted Havana the title of City in 1592 and a royal decree in 1634 recognized its importance by officially designated as the "Key to the New World and Rampart of the West Indies". Havana's coat of arms carries this inscription. The Spaniards began building fortifications, and in 1553 they transferred the governor's residence to Havana from Santiago de Cuba on the eastern end of the island, thus making Havana the de facto capital. The importance of harbour fortifications was early recognized as English, French, and Dutch sea marauders attacked the city in the 16th century. The sinking of the U.S. battleship Maine in Havana's harbor in 1898 was the immediate cause of the Spanish-American War.

Nowadays Havana is the center of the Cuban government, and various ministries and headquarters of businesses are based there.

The founding of Havana

The current Havana area and its natural bay were first visited by Europeans during Sebastián de Ocampo's circumnavigation of the island in 1509.

Conquistador Diego Velázquez de Cuéllar founded Havana on August 25, 1515 on the southern coast of the island, near the present town of Surgidero de Batabanó. Between 1514 and 1519, the city had at least two different establishments. All attempts to found a city on Cuba's south coast failed. The city's location was adjacent to a superb harbor at the entrance to the Gulf of Mexico, and with easy access to the Gulf Stream, the main ocean current that navigators followed when traveling from the Americas to Europe. This location led to Havana's early development as the principal port of Spain's New World colonies. An early map of Cuba drawn in 1514 places the town at the mouth of the river Onicaxinal, also on the south coast of Cuba. Another establishment was La Chorrera, today in the neighbourhood of Puentes Grandes, next to the Almendares River.
