After a few minutes of walking, we finally face the emblem of the city: the unique and prestigious Aqueduct of Segovia. This is one of the most important works that the Romans left as a legacy to the vast empire of Spain. It was built in order to bring water from the Sierra to Segovia.
The assumptions of its construction date back to the 1st century at the time of Flavian, but also at the time of Nerva and Trajan. Failure to date this monument does not prevent it to be at the top of the classification of the best works of Spanish civil engineering.
This extraordinary work in which harmony and beauty mingle, was useful to the city until recently. During the attack directed against Segovia in 1072 by the Muslim Al-Mamun from Toledo, 36 arches were damaged but were restored during the 15th century.
At its creation, two niches were built, probably to protect the pagan gods. Over time, these were replaced by images of Saint Sebastian and the Virgin, as ordered by the Catholic Monarchs. Under these niches was an inscription in bronze, in relation to its creation, where today is only a slight trace of it. Despite many conflicts, the Aqueduct has not been through too much restoration processes over the centuries.
Now some numbers about it. From its starting point in the Sierra de Guadarrama to its other end, the viaduct is nearly 15 km long. His arch spans at 958 meters, with a maximum height of 28.10 meters and has a total of 166 arches.
Major work of modern hydraulic engineering, arches were built with large stones of granite from Guadarrama, linked with each other by their own weight without mortar, with a perfect balance of power. Water was floating in the still existing channel in the top and through the city to get to the Alcázar. The aqueduct was declared “National Monument” in 1884 and “World Heritage Site” in 1985.
