Influenced by the architectural heritage of Colonial Spain, La Havana is listed as a World Heritage Site by UNESCO. Founded in the 16th century, La Havana became the capital of the island thanks to its strategic position facing the Gulf of Mexico. Rapidly becoming the  principal port of "The Americas", the town was fortified to prevent pirate attacks. Its well preserved architecture and ramparts, its Capitole and Plaza de la Revolucion, all bear witness to its Spanish heritage and the turbulent history of this unusual town.
