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 internationally renowned Cathedral Square, originally called Plaza de la Ciénaga (Swamp Square) was built on a marshland plagued with underground streams and very close to the bay, whose waters also penetrated the area. Work on the buildings began in the last quarter of the 18th Century. The church of the Jesuits was granted the category of cathedral in 1789. No one has ever referred to it as Swamp Square since. The two hundred year old cathedral stands in a beautiful square. It is open for services and was declared National Monument.
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.
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.
