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 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 Gran Teatro de La Habana Alicia Alonso (Great Theatre of Havana Alicia Alonso) is one of the architectural jewelry of Havana. It has an incredible neo-baroque façade with the signature of the Belgian architect Paul Belau. Located in a building known as the Galician Centre of Havana, it was inaugurated in 1915 and at the beginnings it was named Tacón Theatre. Not only in its façade there are evidences of its exquisiteness, but also its indoors halls show the luxury and elegance of the time. Its stages have shown the better artistic representations of all times, with outstanding personalities during its history (Sara Bernhardth, Enrico Caruso, Alicia Alonso) The theatre has been home to the Cuban National Ballet and, the main stage of the International Ballet Festival of Havana. Its facilities include theatres, a concert hall, conference rooms, and a video screening room, as well as an art gallery, a choral centre, and several rehearsal halls for danzarias groups and dance companies.

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.
