As the capital of Cuba, Havana is recognized as a UNESCO World Heritage site. It is here that salsa was born in the early 20th century. Dance in the numerous clubs of the city for decades, this music with its caliente rhythms has, in recent years, taken over clubs worldwide. Throughout the last century, Havana has undergone significant changes. Influenced by the United States in the early years, the city has modernized not only in the lifestyle of its inhabitants but also in its architecture. The arrival of Fidel Castro and his political regime in 1959 once again marked a significant shift in the Cuban way of life.
