Start the route at the Aqueduct of Segovia, in Plaza Azoguejo, a meeting point for locals. The aqueduct is highest here. Dating back to the end of the first century, the Roman aqueduct supplied the city of Segovia with water. The water flowed along the canal in the upper level and crossed the city beneath the pavement until it reached the Alcázar. It was given the status of a World Heritage Site in 1985.
