The Padre Tembleque Aqueduct (Acueducto del Padre Tembleque) is considered the most important water supply and distribution system built in the 16th century in the viceroyalty of New Spain. I visited this aqueduct and the archaeological zone of Xihuingo which is located at the foot of the hill of the same name together with Maria, Manni, Pau and our tourist guide Ana who explained us a lot about the relevance and history of these archaeological sites.
