Lisbon Aqueduct
Aqueduto das Águas Livres. Built in 1731-1748.
"The Aqueducto das Aguas Livres, or old aqueduct of Lisbon, 15 1/2 M. in length, was constructed in 1729-49. It supplies the town with the water of the Agtioi Livret from a point near Bellas . The aqueduct, which is partly underground, crosses the valley of the Alcantara at Campolide by a viaduct 1/2 M. long, on the top of which are two stone causeways leading to Bemfica. The largest of the 35 arches is 204 ft. high".--Baedeker 1913
