The Roman aqueduct of Segovia is the town’s main tourist attraction. At the same time its whole construction remain a mystery for there are no documents from the era related to these works, so that basically everything we know about it is through archaeological findings. Please find below the link to a piece of recent information in the English edition of El País written by Aurelio Martin and based upon the findings made by Santiago Martinez Caballero, archaeologist and Director of the Local Museum, which tell us about the definite time of construction, after years of speculation. Enjoy!
