The aqueduct in Segovia, which is little north of Madrid, is the best preserved aqueduct from Roman times.
It was probably built in the first century AD, when the Romans ruled the city and used the city as a military headquarters. The aqueduct was used to bring water into Segovia from Rio Frio, a distance of 17 km. The water was primarily used for public bathing and water sources, then the private bathroom and household.
The aqueduct has no cement holding the 20,400 granite blocks together. Granite blocks coming from the Guadarrama mountain range.
The aqueduct is located in the heart of Segovia and was in use until the 1900s. The aqueduct is 823 meters long. It has 119 arches built with a vaulted and 120 pillars. It has two floors, the upper water went.
Today the aqueduct is a major tourist attraction and a landmark for the city of Segovia. It is subject to ongoing maintenance.
