Portugal - Águas Livres Aqueduct

The Águas Livres Aqueduct, is a baroque architectural infrastructure commissioned by King Dom João V, which was built between 1731 and 1799,. It is a hydraulic structure that stretches over 36 miles, built of cut stone quarried in the Lisbon area, together with limestone masonry. It was the last great classical aqueduct to be built all over the world, constituting a system for the capture and transport of water, which passes through five separate municipalities in Portugal: Amadora, Lisboa, Odivelas, Oeiras and Sintra. It begins in a rural area, in the municipality of Sintra, where it cohabits with cultivated fields and pine groves, and, throughout its length, it crosses urban areas, surrounded by buildings and public roads. In the municipality of Amadora, it runs parallel to the railway line from Sintra to Lisbon.
