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.

Fuente de La India (La India Fountain) is located in a circus in front of the El Capitolio and Saratoga Hotel, in the city of Havana. The fountain is made in Carrara marble and was sculpted by Giuseppe Gaggini in 1837 for the Count of Villanueva. This fountain represents a brilliant indigenous woman, adorned with a crown of eagle feathers, sitting on her throne, and surrounding by four dolphins whose tongues are fountain pouring water on four shells composing its base. She holds with her hand a defense with the crest of the city, and a horn-shaped basket filled with fruits. This sculptural work has been an inspiration for several poets, and also appearing in several fantastic tales.

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.
