The aqueduct of Segovia is a Roman aqueduct that carried water to the Spanish city of Segovia.

Its construction dates from the beginning of the 2nd century AD. C., at the end of the reign of the emperor Trajano or principles of the one of Adriano.

The most visible part, and therefore famous, is the arcade that crosses the Plaza del Azoguejo, in the city.

The Segovia aqueduct conducts the waters of the Fuenfría spring, located in the mountains close to 17 kilometers from the city, in a place called La Acebeda. Travel more than 15 kilometers before reaching the city.

The water is first collected in a cistern known by the name of El Caserón, to then be conducted through a channel of ashlars to a second tower (called Casa de Aguas), where it is decanted and gritted, to continue its journey. Then it goes 813 meters (with a slope of 1%) to the top of Postigo. Before, in the Plaza de Día Sanz, it makes a sharp turn and heads towards the Plaza del Azoguejo, where it saves the depression with an arcade, which presents all the splendor of the monument.

In the highest part it measures 28 meters and has two orders of arches on pillars. In total, it has 167 arches.

It is built with granite ashlars laid without mortar between them.

On the three highest arches there was in Roman times a cartouche with bronze letters showing 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 legend was the founder of the city. In the times of the Catholic Monarchs, the image of the Virgen del Carmen (although many mistakenly believe that it is the Virgen de la Fuencisla, patron saint of the city) and San Sebastián were placed in these two niches. However, today you can only see the first size.
