The Real Force Castle is located in Old Havana, in an attractive area of important architectural, urban, cultural and social values. This is the oldest fortress of the former fortification system of Havana and the Americas, which construction dates back to 1577. It was declared a World Heritage Site by UNESCO. A replica of the La Giraldilla, the symbol of the city, can be seen on the highest tower of the castle (the original is in the Museum of the City). Since 2008, the Museo de Navegación (Maritime Museum) is located in the former moat of the Real Force Castle. This museum houses interesting exhibits detailing the history of the fortress and Old Havana, as well as its connections with the former Spanish Empire. It’s worth mentioning that huge scale model of the Santísima Trinidad galleon can be found here.

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.

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.
