The neighbors of the town insisted to the town council on the need to create a new public square for their amusement. In 1587, the town council decided to use as a public square the area behind the Convento de San Francisco, which was being built at the time. During the latter decades of the 16th century, this square was called the Plaza Nueva (new square), but from the 18th century onwards, once the Plaza del Cristo had been built, it began to become known as the Plaza Vieja (old square). The most remarkable feature of this square are the buildings around it, with their unquestionable historical and artistic importance of having been the blueprint for a style of architecture which, along with certain developments, subsequently spread throughout the city and characterised the Cuban architecture of the 18th century.

The Museo Alejandro de Humboldt (Alejandro de Humboldt Museum) is located in a Colonial house in Plaza de San Francisco de Asís Square, in Old Havana, Cuba. Its name comes from the German scientist Alejandro von Humboldt, who is seen as the second person to discover Cuba. This is a scientific museum dedicated to biology and its main objective is to preserve research and promote the historical Humboldt’s legacy. This institution enhances the labor of Cuban and international personalities whose contributions are considered relevant for the development of culture in general terms. It exhibits the historical trajectory of the scientific and botanic data he compiled throughout the island at the beginning of the 19th century, as well as a botanic exhibition which is fundamentally made up of ferns. In this museum there is a perfect copy of a Kritosaurus skeleton found in the desert and donated by the Mexican government, as well as an enormous Pterosaur skeleton, which is around 10 meters length. The House also has a conference room with capacity for 100 persons and a specialized library on German literature.

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 Cannon Blast ceremony (El Cañonazo de las Nueve) is one of the oldest and attractive traditions of Havana. In colonial days, the shots signalled the closing of the gates of the walled city and the rising of the chain across the entrance to the harbour. The tradition of firing a cannon every night at 9:00 pm was kept even after the wall was torn down and is still used for checking your watch.
