Puerta de Alcalá
The Puerta de Alcalá was built by Sabatini in 1778 as part of the city decoration restorations promoted by Charles III. It is made of granite and is an excellent example of proportion, harmony, and elegance. Sabatini designed a structure consisting of five arches, three of them half-point and another two, placed at the ends, in the form of an architrave. The openings are flanked by ten columns with modern Ionic capitals, ending in cornices crowned by an attic.
