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.

La Bodeguita del Medio is a must-visit, typical restaurant of Havana, and one of the most attractive tourist spots. Old Havana has been frequented by countless visitors, from well-known writers like Ernest Hemingway to important politicians. Its interior offers a typical Cuban atmosphere, as well as excellent music, Creole cuisine (slow-roasted pork, ropa vieja, black beans, yucca with mojo, tostones, arroz morro, etc) and a fantastic typical drink like the mojito. Following the initiative of Leandro García, a journalist who signed the restaurant’s wall, all famous people who visit the place do the same. They leave a memento there in the form of a print, a picture, an object, or some graffiti; it is even possible to find the signatures of some historical figures, like Salvador Allende, Ernest Hemingway, or Pablo Neruda. You can’t miss your chance to visit this place on your way through Habana Vieja. If you don’t book a table in advance you won’t probably have another chance to get one, but you will for sure enjoy an incredible atmosphere surrounded by Cuban history.

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.

A few steps towards Calle Brasil from Plaza del Cristo Square is where the 1886 Museo de la Farmacia Habanera is located. Founded by the Catalonian José Sarrá, it is a shop-museum and nowadays still functions as a pharmacy. The museum displays the history of pharmacies in Havana and their evolution in Cuba. This Pharmacy preserves its original Neo-gothic furniture with Moorish influences, and host a large collection of medicine bottles and medical tools, extracted from archeological excavations in the old city, as well as a book collection with valuable prescriptions for the study of Cuban pharmacopoeia. The museum also exhibits an elegant scale model of an old pharmacy with captivating historical explanations.
