Why is the Cathedral of Havana considered an important example of Italian Baroque design?

The Cathedral of Havana is considered a significant example of Italian Baroque design primarily due to the architectural treatment of its facade.12

The facade is structured by three columns that are turned outward from the center, a technique that creates concave and convex rhythms. This use of fluid, active, and undulating masses is reminiscent of the work of the Italian architect Francesco Borromini, a master of the Baroque style who was known for his inventive transformations of architectural elements.13

Furthermore, the cathedral is situated on an intimate square that is widely regarded by art historians as one of the best-proportioned urban spaces in the Americas, reflecting the Baroque emphasis on integrating buildings with their surrounding environment.13
