Cuba's capital and largest city is Havana. It is situated on a harbour on the island's northern coast that is shielded by a long, thin peninsula. The city is the most populated in the Caribbean with a population of nearly 2.3 million. The Spanish established Havana in 1515, and it swiftly grew into a significant port and trading hub. Spanish colonial rulers significantly fortified the city, which had a significant impact on the Spanish colonial empire. Havana developed as a significant location for the slave trade in the 19th century. Havana was transformed into a communist metropolis following the Cuban Revolution in 1959. The city's economy suffered, and many of its structures deteriorated. But Havana has recently experienced a moment of economic and cultural renaissance. The historic district of the city has been renovated, and tourism has grown. Havana is a city with a vibrant past and present. Numerous structures from the colonial era can be seen there, including the Palacio de los Capitanes Generales, the Catedral of San Cristóbal, and the Castillo de San Carlos de la Cabaa. The city is renowned for its exciting nightlife and music scene.
