Elvas is a town about 10 miles from the Spanish border. It wasn’t a major destination, but we had to stop to see the gigantic aqueduct. At some points there were 5 stacked arches (including the really little arches you can see in the photos). Elvas is a UNESCO world heritage site (The Garrison Border Town of Elvas and its Fortifications). Constructuion of the aqueduct began in the 15th century. It is just about 4 miles long. The trees in the photos are olive trees. Lesson learned: don’t eat unripened olives off the tree…they taste terrible.
