The San Francisco de Asís Church and Convent is the current scenario of the richest cultural traditions. This is one of the most extraordinary convent and church complex of the colonial time. The construction of the current set dates from 1738, and it replaced a more modest one completed in 1591. After a restoration in the nineties, the architectural group has harbored, also, a concert hall and the Holy, Sacred and Religious Art museums.

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.

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.

The Palacio del Segundo Cabo (Segundo Cabo Palace) is located on the north side of Plaza de Armas Square, Old Havana. This majestic palace is Neoclassical in style and was built in 1772 with local limestone full of holes and calcareous marine incrustations. This building was first built as headquarters of the Spanish vice-governor. Currently, and after several reworkings during which it functioned as Post office, Senate Palace, Supreme Court, National Academy of Arts and Letters, or the Cuba Academy of Science, nowaday it belongs to the Cuban Ministry of Culture, and it hosts the Centre for the Interpretation of Cuba-Europa Relationship.
