Cuba is the Caribbean country whose capital is Havana. Havana is Cuba’s largest city and its political, economic, cultural, and historical center.
The city was founded by Spanish colonists in 1519 and grew rapidly because of its protected harbor on Cuba’s northern coast. Its position near the Straits of Florida made it an important stop for Spanish ships traveling between the Americas and Europe.
Havana became the island’s capital in 1552, replacing Santiago de Cuba as the principal colonial administrative center. Its historic core, Old Havana, preserves plazas, churches, fortifications, and buildings reflecting centuries of Spanish colonial rule and later Cuban history.
The other choices are separate Caribbean countries: Barbados has Bridgetown, Haiti has Port-au-Prince, and Jamaica has Kingston. Havana is therefore specifically associated with Cuba, not with the Caribbean region generally.
