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 Cathedral of Havana is an iconic work of what is known as Cuban Baroque and the most remarkable of our colonial churches. The glorious baroque facade and asymmetrical bell-towers of the late 18th-century cathedral are the square’s top attraction. Its interior is surprisingly plain, but it once held the remains­ of Christopher Columbus. Religious services are held here. It has been declared a National Monument.

This is a 1760 Baroque palace venerated for the great beauty of its Andalusian patio. It has a fountain surrounded by tropical vegetation where you will find several tortoises. Before the Revolution, this monumental building was the headquarters of the Industrial Bank; nowadays it houses the El Patio Restaurant. Although it offers traditional Cuban food, it speciality is meat and crustaceous, dishes as the Cathedral Mixed Grill (a varied grill) and skewers of lobsters and shrimps. The bar serves a collection of wines beers, rums and cocktails. It is currently possible to buy souvenirs in the craftworks shop located in the former Casa de Baños House, on the western side of the Cathedral square.

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.
