Finally! A first hand look at the Segovian Aquaduct! Acueducto de Segovia is a Roman aquaduct which was built in the first century. Using little or no mortar, it has stood with little intervention since then. At its tallest, it is 28.5 M or about 93 feet high and its 1% grade brought water to Segovia from the Rio Frio from its inception until the middle of the 19th century. SO TOTALLY impressive! I think of structures built in modern cities which haven't even survived a century of use! A couple of ladies (one of whom was from the Dominican Republic) took my picture in front of the aquaduct and I thank them for that!
