It is built with granite blocks laid without mortar between them. In Roman times, above the three tallest arches there was a cartouche with bronze letters stating the date and the builder. Also at the top you can see two niches, one on each side of the aqueduct. It is known that in one of them was the image of Hercules who, according to one of the legends, was the founder of the city. In the times of the Catholic Monarchs, the image of the Virgin of Carmen was placed in those two niches (although many mistakenly believe that it is the Virgin of Fuencisla, patron saint of the city) and Saint Sebastian "Sebastián (martyr)"). However, today you can only see a resin replica of the first carving, which was replaced in 2019,[6]​ due to the significant deterioration that the original image presented after being outdoors for almost 500 years, even suffering some detachment.[7]​ The original image of the Virgin, now restored, can be seen in the Segovia Mint museum.[8]​ On December 4, festival of Santa Bárbara "Bárbara (saint)"), patron saint of the Artillery Corps, whose academy is in Segovia, the cadets cover the image of the Virgin with a flag. The line of arches rises organized on two floors, with a simple decoration in which simple moldings predominate, which frame and run through the building.

During the time of the Catholic Monarchs, the first major reconstruction work on the aqueduct was carried out. The prior of the nearby Jerónimos del Parral monastery, named Pedro Mesa, was in charge of the works. 36 arches were rebuilt, with great respect for the original work. Later, in the 19th century, the aforementioned statues of the Virgin of Carmen and Saint Sebastian were placed in the central niches.

The aqueduct arch is the most important architectural landmark of the city. It has remained in operation throughout the centuries and perhaps that is why it has survived to this day in perfect condition. Until almost today, it provided water to the city of Segovia, and more specifically to the Alcázar. In recent years it has suffered obvious deterioration caused mainly by environmental pollution and the granite erosion processes themselves. The vehicular traffic near the aqueduct (which still circulated between the arches until 1992) and the holding of concerts and high-volume musical activities at its feet are also facts that harm the monument.[9]​ To guarantee its survival, a meticulous restoration process was carried out in 1992 that lasted almost eight years, under the direction of architect Francisco Jurado.[10]​[11]​ However, it is still exposed to pollution, since traffic continues. a few meters from him.[12]​.
