Towards the end of the 16th Century, the square was known as the Plaza Nueva (New Square), however after the construction of the Plaza Nueva del Cristo (New Square of Christ) in the 18th Century, it was then called Plaza Vieja (Old Square). The buildings that surround this open space are of unquestionable architectural and artistic importance and typify Cuban architecture of the 18th Century. After the complete refurbishment of the central fountain, the square has recovered its original splendour.Place: Ciudad de La Habana. Calle Mercaderes. Old Havana.
The oldest space of the city surrounded by the most important political, military, religious and civil buildings of the town: la Real Casa de Correos (1772-90), Palacio del Segundo Cabo and Palacio de los Capitanes Generales (1776-91). In 1955, a statue of the Father of the Homeland, Carlos Manuel de Céspedes, stands in the center of the square.
The San Francisco de Asís Church and Convent is the current scenario of the richest cultural traditions. As the City Historian has said: “to collect, restore, conserve and exhibit are the classic principles that govern there.... so as to save from the offenses of time the endangered heritage.” The construction of the current set dates from 1738, and it replaced a more modest one completed in 1591. Since it was closed to worship in 1841, the building has seen the most diverse uses. After a restoration that brought back its original values in the nineties, the architectural group has harbored, also, a concert hall and the Holy, Sacred and Religious Art museums.
The castle is located in Old Havana, in an attractive area of important architectural, urban, cultural and social values. It was declared a World Heritage Site by UNESCO and is also the oldest fortress of the former fortification system of Havana. 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).
The origin of this beautiful popular square, situated between San Pedro, Oficios y Amargura streets, goes back to 1628. Two buildings of significant importance flank its large cobbled space: the Convent and the Lesser Basilica, whose tower for many years was considered the highest point of the town. Given its location very close to the bay, it soon became a commercial square and a source of livelihood for the people of Havana. The Covent and the Basilica are now a concert hall and the Museum of Religious Art.
The Castillo de los Tres Reyes del Morro is perhaps the most emblematic of all Cuban fortresses. Its construction began in 1589 and concluded in 1630. In its day it was considered a fundamental piece for defending Havana against corsairs and pirates. The lighthouse was added a few years after its construction (45 m), and is considered the unequivocal distinctive seal of Havana.
