Perhaps the most iconic of all Cuban fortresses. Its construction began in 1589 and was completed in 1630, playing a key role in the defence of Havana against raids by corsairs and pirates.  When the English attacked and captured Havana in the year 1762, the castle was damaged and later as soon as Spain took power again it was rebuilt and modernized. A lighthouse was added to the Morro in 1764. Standing 45 metres above sea level, it has become an unmistakeable symbol of Havana.

The José Lezama Lima House Museum is located in the former house of the Cuban writer José Lezama Lima, in Centro Habana. The museum exhibits several objects belonging to the writer, placed in the same way Lezama had them. The visit to this museum is compulsory for those who wish to get into Cuban literature. In this place were written worldwide known novels, like Paradiso and Oppiano Licario.

The Museo Casa Natal de José Martí (Birthplace Museum) is the house in which José Martí was born, a 19th century politician, intellectual and national hero of the Republic of Cuba. This humble two-floor house was converted into a museum in 1925 and declared a National Monument in 1949. It exhibits personal objects of José Martí, whose spirit is felt in every corner of the restored house. It was built at the beginning of the 19th century, rather close to the city walls, and has typical features of many houses in the area: a tiled roof and mortar walls.  The house was restored and its collection enriched in a community process in 1959. It is interesting to know that this museum contains the only known Oil Portrait of José Martí.

Situated in the former Presidential Palace (1920-1960), the Museum of the Revolution is a colorful building of a large dome and a mixture of styles. A detailed panorama of the struggle undertaken by the Cuban people in order to obtain its freedom is available in its 38 rooms. Its outdoor areas feature the Granma Memorial, where visitors can see, protected by an enormous glass case, the boat on which Fidel Castro and more than eighty combatants returned to Cuba from exile in Mexico to recommence the fight for the country's independence.
