It was built about 2,000 years ago and served its purpose until the 19th century, providing water to Segovia and nearby settlements. Although the aqueduct is 18 km long, only a small section passing through the Azoguejo square is popular with tourists. Due to its active use, the aqueduct in Segovia was often repaired, and therefore retained its almost original appearance, except for the stonework that has been replaced in places.
