The vast Fortaleza de San Carlos de la Cabaña, known as ‘La Cabaña’, running beside the harbor, was constructed after the English capture of Havana in 1763. The largest of the military structures built by Spain in the Americas, this fortress was completed in 1774 and its presence formed an effective complete deterrent against the country's enemies. The polygon, occupying an area of around 10 hectares, consists of bastions, ravelins, moats, covered walkways, barracks, squares and stores.  It is impressively well preserved, and the gardens and ramparts are romantically lit in the evening. This fortress hosts the spectacular nightly ceremony of El Cañonazo de las Nueve (cannon fire at 9), the firing of a cannon that marked the closing of the city gates, one of Havana's longest-held and most attractive traditions.

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.

The monumental Capitolio is a replica of the American capitol in Washington, DC. It is one of the most emblematic buildings of the Havana skyline and it occupies an area of 38 875 m². It was the seat of the legislative body of the Republic since its inauguration on May 20, 1929. The facade is mainly of classic style while the interior of the building is characterized by eclectic opulence. From the stairs on we see the imposing porch columns and behind them we find the main gates, fashioned in bronze with bas-relief depicting important scenes of national history. On both sides of the uppermost part of the stairs there are two bronze statues, symbols of two guiding virtues: people and work. These statues are the work of the Italian sculptor Angelo Zanelli.
