The Roman Aqueduct of Segovia is, without any doubt, one of the best-known archaeological references on a national and international scale and, of course, the symbol of the city of Segovia.
Its mission was, obviously, to provide water to the population of Segovia from the river Frío, at the foot of the Sierra de Guadarrama, and that still in our days is visible throughout the city. The section that saves the height difference at the entrance to the city stands out, with an arcade of 760 meters in length, which in its highest sector consists of two bodies of large arches of granite ashlars, on which the driving of water.
The most recent archaeological excavations carried out at the foot of the monument during its last restoration, have provided data pointing to a date around the end of the first century and the beginning of the second century AD, and more specifically in the time of Trajan, for the last works of construction of the Aqueduct.
The imposing presence of this sector of the Aqueduct has been partly responsible for the fact that, for most people, the Aqueduct is limited to this section of arches, ignoring in a very generalized way the existence of that other part composed of the canalization floor and the manholes or desarenadores that are part of the engineering work, which is the Aqueduct. The archaeological studies on the monument have allowed to define with complete accuracy the complete route of the canalization, whose route constitutes an interesting alternative tourist route for the historical set of Segovia, following the route of the water for the old city, and that begins in the entrance from the city by the road to La Granja, where it is visible at present, an important section of the canalization of the Aqueduct:
1 STONE HOUSE
First desander of the Aqueduct, in the urban area of Segovia. It is a covered construction with pointed vault that contains a decanter pit to remove impurities from the water, and a flow regulation system. It is probably a relatively modern work, from the 15th century or the beginning of the 16th.
2 SOURCE AND TAKE OF WATER TO THE CONVENT OF SAN ANTONIO EL REAL, OLD PALACE OF HUNTING OF THE KING ENRIQUE IV
It is one of the first water easements located from the main channel. It is visible the perforation of the piece of the channel that gave rise to the existence of a pylon at this point, remembered by three carved stones that are still preserved in situ.
3 SECOND DEVELOPER AND START OF THE ARCHERIES SECTION
A sand trap with characteristics similar to those described above is built on two courses of large granite blocks, unequivocally Roman, which speak of the existence of an ancient castellum aquae at this point.
4 SAND HOLDER AND WATER DISTRIBUTOR DOCUMENTED IN THE PLAZA MAYOR
Discovered in the year 1983, it is accessed through a gallery with masonry walls covered with large granite blocks, through which runs the main channel of the Aqueduct. The fate of the diverting flow could not be determined with precision, although the orientation of the water outlet points towards the area of the Cathedral and the Judería neighborhood.
5 LAST SAND HOLDER AND INCOME OF THE CHANNEL IN THE ALCALAZAR VILLAGE
It is the last point with archaeological documentation of the canal. From this point, only the section of the canal carved into the rock is visible, in the wall of the Alcázar moat, under the access gate to the fortress, which was the final destination of the Aqueduct, at least during the time of the Queen Juana.
