Walk through century-old tunnels, see incredible city views and learn more about the one thing we all can’t live without: fresh water.
The Lisbon Aqueduct was built in 1746 to bring the city its first clean drinking water. Lisbon’s remarkable aqueduct is made up of 109 stone arches, which were the tallest stone arches in the world when they were built. Its total length is 58km (36 miles), but the most visible parts are the 14 arches crossing the Alcantara Valley (the best views are from Campolide train station), the tallest of which rise to a spectacular 65m (213ft) from the ground with a span of 29m (95ft). Astoundingly, it all survived the 1755 earthquake.
